Subject [jira] [Commented] (MAPREDUCE-5142) MR AM unregisters with state KILLED when an error causes dispatcher to shutdown
Date Wed, 10 Apr 2013 20:05:15 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5142?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13628187#comment-13628187

Hitesh Shah commented on MAPREDUCE-5142:

@Jason, yes - definitely the same underlying issue. Addressing the CLC creation would address
a part of the issue but currently all uncaught exceptions will end up with the AM in a KILLED

> This happens when for some reason, there is an exception in a state machine's event handler
causing AsyncDispatcher to trigger a shutdown. In such a scenario, even though the AM actually
failed due to some error, its actual state ends up as KILLED.
