I wrote a tool which collects JMX metrics.
Therefore hbase-env.sh has the following:
export HBASE_REGIONSERVER_OPTS="$HBASE_JMX_OPTS
-Dcom.sun.management.jmxremote.port=10102"

I commented in HBASE-2789
<https://issues.apache.org/jira/browse/HBASE-2789>with my addition to
bin/hbase-daemon.sh that synchronizes conf files from
master to RS.

Cheers
