             Summary: Minor optimizations for AMS memory settings
                 Key: AMBARI-13105
                 URL: https://issues.apache.org/jira/browse/AMBARI-13105
             Project: Ambari
          Issue Type: Bug
          Components: ambari-metrics, stacks
    Affects Versions: 2.1.2
            Reporter: Dmytro Sen
            Assignee: Dmytro Sen
             Fix For: 2.1.2


Desired changes:
HBase Xmn size was not adjusted
We could round off the integers to more reasonable size in MB, like 2048 vs 1925 (Not urgent)
Warning message suggested allocating more memory to Xmx but Xmn adjustments are not suggested. Lets decide on maybe taking these out and rely on a ratio. (The original settings were recommendation from HBase team, lets adjust these based on our testing)
The "m" / "g" etc, for heap size parameter is inconsistent (meaning sometime present sometimes not), not sure if this is UI or BE problem
The suggestion that tmp dir should not be on root partition is fine but it should also mention, do not put it on same partition as hbase.rootdir, lets take out the fact that tmp.dir would be cleaned up.
