stack commented on HBASE-2789:
------------------------------
What hadoop mechanism does this Ted? Is it this mechanism in the
hadoop-daemons.sh script that you are referring to:
{code}
if [ "$HADOOP_MASTER" != "" ]; then
echo rsync from $HADOOP_MASTER
rsync -a -e ssh --delete --exclude=.svn --exclude='logs/*'
--exclude='contrib/hod/logs/*' $HADOOP_MASTER/ "$HADOOP_HOME"
fi
{code}
We should add this to the hbase scripts?

> 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.
