Subject [jira] [Commented] (MAPREDUCE-4729) job history UI not showing all job attempts
Date Wed, 17 Oct 2012 21:16:04 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4729?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13478393#comment-13478393
] 

Thomas Graves commented on MAPREDUCE-4729:
------------------------------------------

The jobhistory file itself only has one AM_STARTED event which is for the 4th attempt. So
it must be the jhist file is getting lost of corrupt from the other attempts somehow.

> We are seeing a case where a job runs but the AM is running out of memory in the first
3 attempts. The job eventually finishes on the 4th attempt.  When you go to the job history
UI for that job, it only shows the last attempt.  This is bad since we want to see why the
first 3 attempts failed.
> The RM web ui shows all 4 attempts. 
> Also I tested this locally by running "kill" on the app master and in that case the history
server UI does show all attempts.
