zentol opened a new pull request #7062: [FLINK-10825][tests] Increase request-backoff for high-parallelism e2e test
URL: https://github.com/apache/flink/pull/7062
 
 
   ## What is the purpose of the change
   
   This PR stabilizes the high-parallelism iterations e2e test.
   
   When a task starts running it requests data (partitions) from other tasks. In case of a timeout the request is retried with a backoff, until the maximum backoff (`taskmanager.network.request-backoff.max`) is reached.
   When reached a `PartitionNotFoundException` is thrown as reported in the JIRA that fails the job.
   
   If a job is not fully deployed within the time that it takes 1 task to reach the maximum backoff it is quite likely for this exception to occur.
   
   This PR bumps the maximum backoff to 60 seconds, which should give the job more time to fully deploy.
