Description

-Xmn parameter for HBase RegionServer is calculated with hardcoded value.

This patch allows you to configure values used to calculate this parameter (the maximum value for -Xmn and the ratio between -Xmn and -Xmx).

Without this fix HBase can be crash because of OutOfMemory when you do a YCSB test for example.
