Ted Yu commented on HBASE-2789:
-------------------------------
I added the following to bin/hbase-daemon.sh (at line 171) for sync'ing conf
files upon startup:
if [ "$HBASE_MASTER" != "" ]
then
echo rsync from $HBASE_MASTER
rsync -a -e ssh --delete $HBASE_MASTER:${HBASE_CONF_DIR} ${HBASE_HOME}
fi
It works on a 16 node cluster one of which is the master.

> If HBase config is modified when HBase cluster is running, the changes
> wouldn't propagate to region servers after restarting cluster.
> This is different from hadoop behavior where changes get automatically copied
> to data nodes.
> This feature is desirable when enabling JMX, e.g.
