Subject [jira] [Commented] (MAPREDUCE-4128) AM Recovery expects all attempts of a completed task to also be completed.
Date Thu, 12 Apr 2012 17:13:19 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4128?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13252601#comment-13252601

Bikas Saha commented on MAPREDUCE-4128:

I am rerunning the tests. Does not look like any of them have to do with recovery though.

I would prefer leaving the javac warnings there. If/When we figure out how to fix these then
we dont want to lose any of them because some got hidden with @suppress. If we do decide suppress
them then we could suppress them all in 1 jira for tracking. Sounds good?

> The AM seems to assume that all attempts of a completed task (from a previous AM incarnation)
would also be completed. There is at least one case in which this does not hold. Case being
cancellation of a completed task resulting in a new running attempt.
