Subject [jira] [Commented] (MAPREDUCE-4693) Historyserver should provide counters for failed tasks
Date Wed, 27 Feb 2013 20:59:13 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4693?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13588741#comment-13588741
] 

Siddharth Seth commented on MAPREDUCE-4693:
-------------------------------------------

The latest patch (MAPREDUCE-4693.4.patch) looks good. +1 
There's a couple of follow up tasks which may be required though. Job level counters in case
of job failure. Task.selectBestAttempt needs a fix.

> Currently the historyserver is not providing counters for failed tasks, even though they
are available via the AM as long as the job is still running.  Those counters are lost when
the client needs to redirect to the historyserver after the job completes.
