> 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.
