[jira] [Created] (YARN-3643) Provide a way to store only running applications in the state store

Karthik Kambatla created YARN-3643:
--------------------------------------

             Summary: Provide a way to store only running applications in the state store
                 Key: YARN-3643
                 URL: https://issues.apache.org/jira/browse/YARN-3643
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: resourcemanager
    Affects Versions: 2.7.0
            Reporter: Karthik Kambatla


Today, we have a config that determines the number of applications that can be stored in the state-store. Since there is no easy way to figure out the maximum number of running applications at any point in time, users are forced to use a conservative estimate. Our default ends up being even more conservative.

It would be nice to allow storing all running applications with a conservative upper bound for it. This should allow for shorter recovery times in most deployments.
