Subject [jira] [Commented] (MAPREDUCE-3921) MR AM should act on the nodes liveliness information when nodes go up/down/unhealthy
Date Mon, 09 Apr 2012 15:21:17 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3921?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13249867#comment-13249867
] 

Robert Joseph Evans commented on MAPREDUCE-3921:
------------------------------------------------

Someone pointed out to me that my comment is a bit confusing.  When I said two nodes going
down very close to one another I meant that for this to happen we would need one node to go
down in succession that had the correct processes running on them.   But now that I think
about it more, I am not even sure if it will expose the issue.
