>             Project: Ambari
>          Issue Type: Bug
>            Reporter: Andrew Onischuk

> PROBLEM: Ambari does not manage mapred-env.sh and JobHistory memory cannot be
> set via Ambari.
> BUSINESS IMPACT: Users are not sure how to change JobHistory memory settings
> in Ambari cluster. This came from eBay so looks like large clusters need to be
> able to increase memory.
> STEPS TO REPRODUCE: navigate to Services -> Mapreduce -> Configs tab and you
> will notice that JobHistory Heap configuration is not there.
> ACTUAL BEHAVIOR: Cannot change JobHistory memory in Ambari UI
> EXPECTED BEHAVIOR: To be able to manage JobHistory memory in Ambari UI
> SUPPORT ANALYSIS: Since Ambari does not manage mapred-env.sh you can manually
> edit config in mapred-env.sh. I verified by manually setting the memory and
> restarting cluster via Ambari that config value did not change.
