LOST/DECOMMISSIONED/SHUTDOWN state , recover to corresponding finished state. > 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 > Components: resourcemanager > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
