>
> In master branch master acts also as regionserver hosting 'hbase:meta' table
> and it has ephemeral znode created in '/hbase/rs'. Because of this
> rolling-restart.sh --graceful will pick up master server from zk at this line:
> {code}
> online_regionservers=`$bin/hbase zkcli ls $zkrs 2>&1 | tail -1 | sed "s/\[//"
> | sed "s/\]//"`
> {code}
> and will restart it a long with rest of regionservers.
> I'm planing to add some code to rolling-restart.sh script to filter master
> server from above list.
