> Ambari GUI for HBase config incorrectly describes the -Xmn as the “maximum
> value for the minimum heap size”, which is incorrect. Xmn is the size of the
> heap for the young generation.
> If somebody new to Java just reads the Ambari description and set both Xmn
> and Xmx to the same value, HBase will start but it will perform miserably.
> Please fix the documentation for the two settings in Ambari GUI that refer to
> Xmx (the ratio and the static value)
