Subject [jira] [Created] (AMBARI-5485) Ambari should Manage JobHistory Heap Size
Date Wed, 16 Apr 2014 17:52:20 GMT
Andrew Onischuk created AMBARI-5485:

             Summary: Ambari should Manage JobHistory Heap Size
                 Key: AMBARI-5485
             Project: Ambari
          Issue Type: Bug
            Reporter: Andrew Onischuk
            Assignee: Andrew Onischuk
             Fix For: 1.6.0

PROBLEM: Ambari does not manage 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 you can manually
edit config in I verified by manually setting the memory and
restarting cluster via Ambari that config value did not change.
