--------------------------------------

             Summary: When work-preserving restart is enabled, the scheduler should wait for the earlier of recovery completion and configured wait time
                 Key: YARN-4679
                 URL: https://issues.apache.org/jira/browse/YARN-4679
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: resourcemanager
            Reporter: Karthik Kambatla


When work-preserving restart is enabled, it appears the restart (or failover) is unconditionally blocked for the configured delay even if the recovery itself finishes sooner than this. This should be updated to wait for the earlier of the two conditions. Also, it would be nice to allow setting the config to -1 to indicate wait as long as need for the recovery to be completed.
