[jira] [Created] (YARN-2567) Add a percentage-node threshold for RM to wait for new allocations after restart/failover

Vinod Kumar Vavilapalli created YARN-2567:
---------------------------------------------

             Summary: Add a percentage-node threshold for RM to wait for new allocations after restart/failover
                 Key: YARN-2567
                 URL: https://issues.apache.org/jira/browse/YARN-2567
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Vinod Kumar Vavilapalli
            Assignee: Vinod Kumar Vavilapalli


This is the remaining part of YARN-2001 - to halt allocations after restart till x% of nodes sync back with the RM. This is useful for avoiding bad scheduling during the time the nodes are still joining back after a restart/failover.
