> When running rolling-restart.sh --graceful we are using graceful_stop.sh to
> unload/restart/load regionserver. For every restarted regionserver we are
> making two calls in graceful-stop.sh to hbase shell to disable/enable
> balancer. This means if we have 100 regionservers to restart by
> rolling-restart.sh --graceful we will make 200 calls to hbase shell. Instead
> i propose that we add optional parameter in graceful_stop.sh that will tell
> script not to manage balancer and manage balancer states in
> rolling-restart.sh when running with --graceful parameter.
