Upgrade from V3.3.4, V3.3.5 to V3.3.6

Upgrade the Docker version to 20.10.x or above.

Steps to upgrade the Docker version:

1. Uninstall the current Docker:

yum remove -y docker-ce docker-ce-cli containerd.io

2. Install the latest version of Docker:

yum install -y docker-ce docker-ce-cli containerd.io

• To install a specific version of Docker:

yum install -y docker-ce-24.0.5 docker-ce-cli-24.0.5 containerd.io

• Replace 24.0.5 with the appropriate version string
• To list specific versions of docker

yum list docker-ce --showduplicates | sort -r

3. Start Docker:

systemctl start docker

Upgrade Steps from Pulse V3.3.4, V3.3.5, to V3.3.6

1. Update Configuration: Change the ImageTag in $AcceloHome/config/accelo.yml to 3.3.6.

2. Push Configuration Update: Execute accelo admin database push-config -a to update the configuration in the database.

3. Back Up and Update CLI:

   • Back up the current accelo file. Download and update to the latest accelo.linux CLI version.
   • Make the new accelo CLI executable with:

mv accelo.linux accelo

chmod +x ./accelo

4. Online Installations: Log in to Docker and download the latest binaries:

accelo login docker

accelo pull all

• Confirm the download by pressing 'Y' when prompted.

5. Offline Installations: Download the latest image packs. Use docker load -i to upload the latest images.
6. Update Configuration Files: Apply new keys in vars.yml and push updated configurations to MongoDB with:

accelo reconfig cluster

accelo admin database push-config

7. Restart Containers: Restart all containers, including databases, using accelo restart all -d.
8. Manage Hydra Agent:

• Uninstall any existing hydra agent with accelo uninstall remote.
• Install the hydra agent afresh with accelo deploy hydra.

9. Finalize Upgrade: Reconfigure the cluster to apply updated configurations for agents by running accelo reconfig cluster -a.

Optional Migration Steps for Pulse Versions Below 3.3.6

These steps are relevant for Pulse installations prior to version 3.3.6 that include an Oozie Server using Oracle DB for metadata storage.

1. Edit Configuration File: Navigate to $AcceloHome/config and open the acceldata_<clustername>.conf file for editing with:

vi $AcceloHome/config/acceldata_<clustername>.conf

2. Modify Oozie Connector Configuration: Locate the oozie.connectors section. Initially, it appears as follows:

oozie.connectors = [

{

  name = "oozie-connector"

  type = "others"

  queryBatchLimit = 100

  thread.pool.size = 10

  pollIntervalMins = 2

​

  driver = "oracle.jdbc.OracleDriver"

  url = "jdbc:oracle:thin:@//<OOZIE DB HOST>:<OOZIE DB PORT>/xe?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false"

​

  user = "oozie"

  pass = "BIfSPHgYPE8iZ+0eJI+5yg=="

  encrypted = true

  timezone = "Asia/Kolkata"

  }

]

• Update the type from others to oracle to reflect the use of Oracle DB. The modified section would look like:

oozie.connectors = [

{

  name = "oozie-connector"

  type = "oracle"

  queryBatchLimit = 100

  thread.pool.size = 10

  pollIntervalMins = 2

​

  driver = "oracle.jdbc.OracleDriver"

  url = "jdbc:oracle:thin:@//<OOZIE DB HOST>:<OOZIE DB PORT>/xe?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false"

​

  user = "oozie"

  pass = "BIfSPHgYPE8iZ+0eJI+5yg=="

  encrypted = true

  timezone = "Asia/Kolkata"

  }

]

3. Save Changes: After making the adjustments, save and close the file.
4. Apply Configuration Update: To finalize the changes, execute accelo reconfig cluster to reconfigure the cluster with the updated settings. The Oozie connectors will appear as follows:

oozie.connectors = [

{

  name = "oozie-connector"

  type = "oracle"

  queryBatchLimit = 100

  thread.pool.size = 10

  pollIntervalMins = 2

​

  driver = "oracle.jdbc.driver.OracleDriver"

  url = "jdbc:oracle:thin:@//<OOZIE DB HOST>:<OOZIE DB PORT>/xe?TNS_ADMIN=/etc/adw"

​

​

  user = "oozie"

  pass = "BIfSPHgYPE8iZ+0eJI+5yg=="

  encrypted = true

  timezone = "Asia/Kolkata"

  }

]
