What is the purpose of the change

(For example: This pull request makes task deployment go through the blob server, rather than through RPC. That way we avoid re-transferring them on each deployment (during recovery).)

Brief change log

(for example:)

  • The TaskInfo is stored in the blob store on job creation time as a persistent artifact
  • Deployments RPC transmits only the blob storage reference
  • TaskManagers retrieve the TaskInfo from the blob cache

  • Extended integration test for recovery after master (JobManager) failure
  • Added test that validates that TaskInfo is transferred only once across recoveries
  • Manually verified the change by running a 4 node cluser with 2 JobManagers and 4 TaskManagers, a stateful streaming program, and killing one JobManager and two TaskManagers during the execution, verifying that recovery happens correctly.
