Iyappan Srinivasan commented on MAPREDUCE-1032:
-----------------------------------------------
Please check this works for both capacity scheduler and default scheduler.
> taskcontroller.cfg should be checked before task tracker comes up

> Key: MAPREDUCE-1032
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-1032
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: contrib/capacity-sched
> Affects Versions: 0.22.0
> Reporter: Iyappan Srinivasan
>
> Right now, task-controller.cfg should have two mandatory parameters
> mapreduce.cluster.local.dir and hadoop.log.dir, without which cluster comes
> up including Task tracker , but when any jobs are submitted, it gives errors.
> This will highly confuse the Ops and end-user.
> Even though, when every job is submitted, task-controller.cfg is checked, it
> should be checked in the very beginning when Task tracker comes up.
> Expected behaviour is :
> 1) TT should not come up.
> 2) TT logs should show why its not come up like which parameter is missing
> and if found, if the values mismatches with the mapred-site.xml
