[jira] [Commented] (MAPREDUCE-6773) Implement RM Container Reuse
Requestor to handle the reuse containers for resource requests
[ https://issues.apache.org/jira/browse/MAPREDUCE-6773?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17246463#comment-17246463 ]

--------------------------------------
Hi [~devaraj]
I see that containers are reused only if priority is PRIORITY_MAP and PRIORITY_REUDCE. currently containers are not even cleaned up if its not any of these priority due to which job hangs whenever containers are killed as NM restarted[as tasks are not assigned to container]. Is there any reason why containers with priority PRIORITY_FAST_FAIL_MAP are not being reused?
{quote}RMContainerReuseRequestor ln no 133, we are checking for PRIORITY_MAP and PRIORITY_REDUCE what about other priorities ? do we need to send CONTAINER_REMOTE_CLEANUP,
