After upgrading your cluster

After upgrading your cluster, you need to update the Flink job dependencies, and restart your Flink and SQL stream jobs on the new clusters.

Updating Flink job dependencies
When you migrate your Flink jobs to a cluster that has a new supported version of Flink, the applications need to use a new version of the artifacts provided by the Flink deployment in your cluster. To avoid incompabilities between the packaged artifacts of your application and the artifacts provided by the Flink cluster, ensure that the POM file of the application is updated to match the Flink version of the new CDP Private Cloud Basecluster.
Resuming Flink applications
After updating the Cloudera Streaming Analytics artifacts, you can resume your application by the Flink run command. In case you have stopped your application by creating a savepoint, you must add the savepoint location to the command.
Importing a project
You can use a Git repository to import a SQL Stream Builder project that was previously created and exported using source control.
Resuming SQL jobs
After upgrading the SQL Stream Builder service in Cloudera Manager, resume your SQL jobs by restarting them using the SQL jobs page of Streaming SQL Console.
