AWS High Availability Incorta Cluster Upgrade Guide

Guide: Upgrade a High Availability Incorta Cluster in AWS

Whereas the AWS High Availability Incorta Cluster Guide describes how to install, configure, and deploy a high availability (HA) Incorta Cluster in Amazon Web Services (AWS), this guide describes how to upgrade your AWS High Availability Incorta Cluster so that Incorta as a Unified Data Analytics Platform is continuously available.

High level summary of the Incorta Cluster Upgrade Procedure

Here is a high level summary of the this upgrade procedure:

  • Pause all scheduled jobs for all cluster tenants
  • Upgrade the Cluster Management Console (CMC)
  • Upgrade LoaderService_1
  • Upgrade AnalyticsService_1
  • Upgrade LoaderService_2
  • Upgrade AnalyticsService_2
  • Upgrade Apache Spark
  • Resume all scheduled jobs for all cluster tenants

Assumptions

As this guide is based on the AWS High Availability Incorta Cluster Guide, it contains assumptions about your cluster typology in AWS.

EC2 Host Configuration Details

Only 5 of the 7 EC2 hosts run Incorta HA Nodes and 1 EC2 runs the Cluster Management Console. Two EC2 hosts run Apache ZooKeeper and are not part of this cluster upgrade guide.

EC2 Host IP and DNS Addresses

Each EC2 Host in this public facing cluster has a:

  • Private DNS
  • Private IP
  • Public DNS (IPv4)
  • IPv4 Public IP
EC2 Host Private DNS Private IP Public DNS (IPv4) IPv4 Public IP
Host_1 <HOST_1_Private_DNS> <HOST_1_Private_IP> <HOST_1_Public_DNS_IPv4> <HOST_1_IPv4_Public_IP>
Host_2 <HOST_2_Private_DNS> <HOST_2_Private_IP> <HOST_2_Public_DNS_IPv4> <HOST_2_IPv4_Public_IP>
Host_3 <HOST_3_Private_DNS> <HOST_3_Private_IP> <HOST_3_Public_DNS_IPv4> <HOST_3_IPv4_Public_IP>
Host_4 <HOST_4_Private_DNS> <HOST_4_Private_IP> <HOST_4_Public_DNS_IPv4> <HOST_4_IPv4_Public_IP>
Host_5 <HOST_5_Private_DNS> <HOST_5_Private_IP> <HOST_5_Public_DNS_IPv4> <HOST_5_IPv4_Public_IP>

EC2 Hosts, Nodes, Users, Applications, and Services

Here is a list of the EC2 Hosts, Nodes, Applications, and Services:

EC2_Host Node Name Application / Service Name
Host_1 n/a
  • Cluster Management Console
  • MySQL 5.6
  • Apache Spark
Host_2 LoaderNode_1 LoaderService_1
Host_3 LoaderNode_2 LoaderService_2
Host_4 AnalyticsNode_1 AnalyticsService_1
Host_5 AnalyticsNode_2 AnalyticsService_2

Secure Shell Access to the AWS EC2 Hosts

This guide assumes that you can readily access 5 of the 7 EC2 hosts using a bash shell terminal that supports both Secure Shell (SSH) and Secure Copy File (SCP) with a shared Key Pair (PEM) file.

In PuTTY or another Windows SSH client, you can create and save a SSH connection for each of EC2 Hosts.

Create Shell Variables for Mac OS or Linux

To expedite secure shell access from either Mac OS or Linux and the EC2 Hosts, create the following variables to store the IPv4_Public_IP values for each host. The Public IPs in the following listing are for illustration.

HOST_1=34.155.100.1
HOST_2=34.155.100.2
HOST_3=34.155.100.3
HOST_4=34.155.100.4
HOST_5=34.155.100.5

Copy the Incorta Package Zip

This guide assumes that you have already downloaded the incorta-package-<new-version>.zip file and can securely copy this file using scp. To copy the incorta-package-<new-version>.zip from your local Documents directory to the tmp directory on each EC2 Host, here are example scp shell commands:

cd ~/Documents
scp -i ~/.ssh/<ssh-auth-file>.pem incorta-package-<new-version>.zip \ incorta@${HOST_1}:/tmp/incorta-package-<new-version>.zip
scp -i ~/.ssh/<ssh-auth-file>.pem incorta-package-<new-version>.zip \ incorta@${HOST_2}:/tmp/incorta-package-<new-version>.zip
scp -i ~/.ssh/<ssh-auth-file>.pem incorta-package-<new-version>.zip \ incorta@${HOST_3}:/tmp/incorta-package-<new-version>.zip
scp -i ~/.ssh/<ssh-auth-file>.pem incorta-package-<new-version>.zip \ incorta@${HOST_4}:/tmp/incorta-package-<new-version>.zip
scp -i ~/.ssh/<ssh-auth-file>.pem incorta-package-<new-version>.zip \ incorta@${HOST_5}:/tmp/incorta-package-<new-version>.zip

Upgrade Requirements

Prior to upgrade, your Incorta Cluster must be operating in good health. You must have already securely copied the incorta-package-<new-version>.zip file to all 5 EC2 hosts that run Incorta (CMC and Incorta Nodes). In order to backup your existing installation, you must also have adequate disk space on each EC2 host.

Prior to upgrade, it is also highly recommended that you first review the Release Notes for the new version

Notice Notebook Add-on

Currently, the Notebook Add-on does not support an Incorta High Availability Cluster. The Notebook Add-on is an Incorta Labs feature. To learn more, review the Notebook Add-on documentation.

Ability to sign in to the Cluster Management Console (CMC)

Using either Google Chrome or Mozilla Firefox, open a web browser with two tabs. In the first browser tab, navigate to the CMC (http://\<HOST_1_IPv4_Public_IP>:6060/cmc/) and sign in with the Administrator username and password.

Ability to sign in to the Incorta Unified Data Analytics Platform via the Classic Load Balancer DNS

In the second browser tab, navigate to the Incorta Unified Data Analytics Platform through the Classic Load Balancer (<ClassicLB_DNS>:8080/incorta/#/login) URL and sign in to the exampleTenant as the Tenant administrator user with the administrator username and password.

Ability to verify high availability throughout the upgrade

This guide assumes that you have the exampleTenant with installed Sample Data. During the cluster upgrade procedure, you will verify the high availability of the cluster by loading the SALES schema and viewing the Sales Executive Dashboard.


Pause all scheduled jobs for all cluster tenants

Prior to upgrading the Cluster Management Console, be sure to pause all scheduled jobs for all cluster tenants. Here are the steps to pause all scheduled jobs for each cluster in the CMC:

  • Sign in to the CMC as the CMC Administrator user..
  • In the Navigation bar, select Clusters.
  • In the cluster list, select a cluster name.
  • Select the Tenants tab.
  • For each tenant in the cluster list…

    • Select Configure.
    • In the left pane, select Data Loading.
    • In the right pane, toggle Pause Scheduled Jobs to enabled.
    • Select Save.
  • Sign out of the CMC.

Upgrade the Cluster Management Console (CMC)

This procedure uses the CMC as configured in AWS High Availability Cluster as an illustration. Incorta Administrators use the CMC to create and manage one or more Incorta Clusters, including:

  • Incorta HA Nodes
  • Incorta Services
  • Server Configurations
  • Default Tenant Configurations
  • Tenants

Activities not to perform during CMC upgrade

While upgrading the CMC, do not perform the following CMC activities:

  • Create or delete a Cluster
  • Add or remove Incorta Nodes
  • Add or remove an Incorta Service to an Incorta Node
  • Start, stop, or restart Incorta Services
  • Edit Server Configurations
  • Edit Default Tenant Configurations
  • Edit Tenant Configurations for a specific tenant
  • Create or delete a Tenant
  • Enable or disable a Tenant
  • View or download log files

CMC shell scripts

To manage the CMC from the command line interface, use the following bash shell scripts. The default directory for these scripts is /home/incorta/IncortaAnalytics/cmc. Here are the related scripts:

  • stop-cmc.sh — stops the CMC
  • start-cmc.sh — starts the CMC

Summary of CMC upgrade procedure

Here is a summary of the steps to upgrade the CMC:

  • Secure shell in to the EC2 host, Host_1
  • Use the CLI to stop the CMC
  • Create a backup of the CMC directory
  • Create a backup of the MySQL metadata database
  • Unzip the installation package
  • Run the Incorta Installer
  • Use the Incorta Installer to upgrade and start the CMC
  • Verify the CMC upgrade
  • Upgrade the Incorta Metadata Database
  • Exit the EC2 host

Secure shell in to the EC2 host, Host_1

Secure Shell into the EC2 host, HOST_1, as the incorta user and change to the CMC directory:

ssh -i ~/.ssh/<ssh-auth-file>.pem incorta@${HOST_1}
cd ~/IncortaAnalytics/cmc

Use the CLI to stop the CMC

Stop the CMC with the stop-cmc.sh shell script:

./stop-cmc.sh

Create a backup of the CMC directory

  • Change to the IncortaAnalytics directory and create a backup of the cmc directory:
cd ..
tar -cvf /tmp/cmc-<old-version>.tar.gz cmc

Create a backup of the MySQL metadata database

  • To create a backup of the incorta_metadata database, use mysqldump command line utility. Here is example with the MySql user as root with the password incorta_root:
mysqldump -uroot -pincorta_root incorta_metadata > /tmp/incorta_metadata.bak

Unzip the installation package

  • Change to the /tmp directory:
cd /tmp
  • Create the incorta directory if it is not already present:
mkdir incorta-package-<new-version>
  • Unzip the incorta package:
unzip incorta-package-<new-version>.zip -d incorta-package-<new-version>

Run the Incorta Installer

  • Run the Incorta Incorta Installer:
cd incorta-package-<new-version>
java -jar incorta-installer.jar -i console

Use the Incorta Installer to upgrade and start the CMC

  • In the Installation Wizard, enter the following values:
Welcome                    : Enter
Copyright                  : Enter
Copyright/License          : Y
Installation Type          : 2- Upgrade
Installation Set           : 2- Custom
Incorta HA components      : 1- Central Management Console (CMC)
Choose Installation Folder : Enter (default)
Start CMC                  : 1- Start CMC
Installation Status        : Enter

Verify the CMC upgrade

  • Return to your web browser in the CMC tab of your web browser.
  • In the Sign-in page of the CMC, verify the upgrade version.

Upgrade the Incorta Metadata Database

  • Sign in to the CMC using the CMC Administrator username and password, for example:

    USERNAME : admin
    PASSWORD : Incorta#1
  • In the Navigation bar, select Clusters.
  • For a Cluster in the CMC, select Upgrade Cluster Metadata.

Note:

A dialog indicates to restart the Incorta Services. You will manually stop and start the Incorta Services using scripts. In the dialog, select OK.

Exit the EC2 host

  • Now that the CMC is running and the Incorta Metadata Database is upgraded, you can exit EC2 Host_1:
exit

Exiting the EC2 host, Host_1, completes the upgrade of the CMC.


Upgrade the Incorta Nodes

An Incorta HA Node shows a status of being online when the Incorta Node Agent and its associated Export Server are running. An Incorta HA Node runs at least one Incorta Node Service, such as a Analytics Service or Loader Service Add-on.

To manage Incorta HA Nodes and Incorta Services from the command line interface, use the following bash shell scripts in the default directory, /home/incorta/IncortaAnalytics/IncortaNode:

  • listServices.sh -all — lists services associated with the current Node
  • stopService.sh <service_name> — stops the named service
  • startService.sh <service_name> — starts the named service
  • nodeAgent/agent.sh status — view the status of an Incorta HA Node
  • stopNode.sh — takes a Node offline, stopping the Node Agent and the export server
  • startNode.sh — brings a Node online, starting the Node Agent and the export server

Upgrade Apache Spark

In this cluster typology, in addition to the CMC and MySQL Server, EC2 Host_1 also runs Apache Spark as a standalone instance.

Incorta requires a specific build version of Apache Spark. The easiest way to upgrade a standalone version of Apache Spark is to follow the procedure for installing an Incorta HA Node as the required Spark files reside in the directory, IncortaNode/spark.

Because the CMC was already upgraded on Host_1, the Incorta Installer is already available to run in console mode. Here is a summary of the steps to upgrade Apache Spark on Host_1:

  • Secure shell in to the EC2 Host that is running the CMC (Host_1)
  • Stop Apache Spark
  • Create a backup of the IncortaNode directory
  • Run the Incorta Installer
  • Use the Incorta Installer to upgrade the Incorta HA Node
  • Stop the Incorta Node Agent
  • Update the Apache Spark configuration files
  • Use the CLI to start Apache Spark
  • Verify that the Apache Spark Master and Worker nodes are running
  • Exit the EC2 host

Secure shell in to the EC2 Host_1 as the incorta user and change to the IncortaNode directory:

ssh -i ~/.ssh/<ssh-auth-file>.pem incorta@${HOST_1}
cd ~/IncortaAnalytics/IncortaNode

Use the CLI to stop Apache Spark

  • Stop Apache Spark with the stopSpark.sh shell script.

    ./stopSpark.sh

Create a backup of the IncortaNode directory

  • Create a backup file of the Incorta Node directory:
cd ~/IncortaAnalytics
tar -czvf /tmp/IncortaNode-<old-version>.tar.gz IncortaNode

Run the Incorta Installer

  • From the unzip directory, you can now run the Java incorta-installer JAR file:
cd /tmp/incorta-package-<new-version>/
java -jar incorta-installer.jar -i console

Use the Incorta Installer to upgrade the Incorta HA Node

  • In the Incorta Installer console, enter these exact values:
Welcome                     : Enter
License Agreement/Copyright : Enter
License Agreement/Copyright : Y
Installation Type           : 2- Upgrade
Installation Set            : 2- Custom
Incorta HA components       : 2- Incorta HA Node
Choose Installation Folder  : Enter- Default
Installation Status         : Enter

Stop the Incorta Node Agent

The Incorta Installer automatically starts the Incorta Node Agent. The Incorta Node Agent does not need to run on this EC2 Host and needs to be stopped:

  • To stop the Incorta Node Agent, execute the stopNode.sh shell script:
cd ~/IncortaAnalytics/IncortaNode/
./stopNode.sh
  • Verify that the Node Agent is stopped:
./nodeAgent/agent.sh status
  • Review the console output.

    Agent is not running in /home/incorta/IncortaAnalytics/IncortaNode/nodeAgent

- Update the Apache Spark configuration files

Both the spark-env.sh and spark-default.conf files need to update the EC2 Host IP addresses.

  • To update spark-env.sh, execute the following bash shell commands:
HOST_1_Public_DNS_IPv4=<HOST_1_Public_DNS_IPv4>
HOST_1_Private_DNS=<HOST_1_Private_DNS>
echo $HOST_1_Public_DNS_IPv4
echo $HOST_1_Private_DNS

cd ~/IncortaAnalytics/IncortaNode/spark/

sed -i "s/SPARK_PUBLIC_DNS=.*/SPARK_PUBLIC_DNS=${HOST_1_Public_DNS_IPv4}/g" conf/spark-env.sh
sed -i "s/SPARK_MASTER_IP=.*/SPARK_MASTER_IP=${HOST_1_Private_DNS}/g" conf/spark-env.sh
  • Verify the updated values for SPARKPUBLICDNS and SPARKMASTERIP
cat conf/spark-env.sh
  • To update spark-defaults.conf, edit the file directly using vi or vim:
vim conf/spark-env.sh
  • Update spark.master to use the value of <*HOST_1_Private_IP**>. Also update the following settings with the appropriate values:

    • spark.cores.max
    • spark.executor.cores
    • spark.sql.shuffle.partitions
    • spark.driver.memory
spark.master                     spark://<HOST_1_Private_IP>:7077
spark.eventLog.enabled           true
spark.eventLog.dir               /home/incorta/IncortaAnalytics/IncortaNode/spark/eventlogs
spark.local.dir                  /home/incorta/IncortaAnalytics/IncortaNode/spark/tmp
spark.executor.extraJavaOptions
-Djava.io.tmpdir=/home/incorta/IncortaAnalytics/IncortaNode/spark/tmp
spark.driver.extraJavaOptions
-Djava.io.tmpdir=/home/incorta/IncortaAnalytics/IncortaNode/spark/tmp
spark.cores.max                  2
spark.executor.cores             2
spark.sql.shuffle.partitions     2
spark.driver.memory              6g
spark.port.maxRetries            100

Use the CLI to start Apache Spark

To start the both the Apache Spark Master and Worker nodes, execute the startSpark.sh shell script:

cd ~/IncortaAnalytics/IncortaNode
./startSpark.sh

Verify that Apache Spark is running

  • In your web browser, enter the URL for Apache Spark such as http://<HOST_1_IPv4_Public_IP>:9091

This completes the Apache Spark upgrade.

Resume all scheduled jobs for all cluster tenants

Now that you have upgrade all Incorta Nodes, the Incorta CMC, and Apache Spark, you can resume all scheduled jobs that were paused earlier. To resume the scheduled jobs, follow these steps:

  • Sign in to the CMC as the CMC Administrator user.
  • In the Navigation bar, select Clusters.
  • In the cluster list, select a cluster name.
  • Select the Tenants tab.
  • For each tenant in the cluster list…

    • Select Configure.
    • In the left pane, select Data Loading.
    • In the right pane, toggle Pause Scheduled Jobs to disabled.
    • Select Save.
  • Sign out of the CMC.

Conclusion

Throughout the upgrade process of your AWS High Availability Incorta Cluster, it is possible to ensure that Incorta as a Unified Data Analytics Platform is continuously available by following these steps:

  • Pause all scheduled jobs for all cluster tenants
  • Upgrade the CMC
  • Upgrade LoaderService_1
  • Upgrade the AnalyticsService_1
  • Upgrade LoaderService_2
