    Component/s: jobtracker

> Jobtracker continues even if History initialization fails

>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-881
>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>          Components: jobtracker

> 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.
