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.
> job history UI not showing all job attempts

> Key: MAPREDUCE-4729
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4729
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: jobhistoryserver
> Affects Versions: 0.23.3
> Reporter: Thomas Graves
>
> 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.
