Jian He commented on YARN-1041: ------------------------------- thanks for the comments, will update the patch once YARN-1490 gets in > Protocol changes for RM to bind and notify a restarted AM of existing > containers > -------------------------------------------------------------------------------- > > Key: YARN-1041 > URL: https://issues.apache.org/jira/browse/YARN-1041 > Project: Hadoop YARN > Issue Type: Sub-task > Components: resourcemanager > Affects Versions: 3.0.0 > Reporter: Steve Loughran > Assignee: Jian He > Attachments: YARN-1041.1.patch > > > For long lived containers we don't want the AM to be a SPOF. > When the RM restarts a (failed) AM, it should be given the list of containers > it had already been allocated. the AM should then be able to contact the NMs > to get details on them. NMs would also need to do any binding of the > containers needed to handle a moved/restarted AM. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
