--------------------------------------
Sharad, is this still valid?
> Jobtracker continues even if History initialization fails

> Key: MAPREDUCE-881
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-881
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: jobtracker
> Reporter: Sharad Agarwal
>
> If there is some problem in the configuration, Job history initialization
> fails. JobHistory#init catches the exception and disable the history. This
> leads to job history not working as expected. However administrators won't
> notice that there is some problem in the config due to which history got
> disabled, unless they see the logs. Better approach would be to not catch the
> exception and let Jobtracker fail to come up if there is error in
> initialization.
