--------------------------------------
Yep. We do this everywhere else in this script. This is the only exception.
Going to commit in a few.

> When rolling-restart.sh script stop master it enters loop trying to detect
> that master znode is deleted. Since it is unable to execute check command
> script hangs in infinite loop. Problematic line of script is:
> while ! bin/hbase zkcli stat $zmaster 2>&1 | grep "Node does not exist"; do
> "bin/hbase zkcli stat" can not be executed since script is run from bin
> directory. My suggestion is that this line should be like this in order to
> work:
> while ! "$bin"/hbase zkcli stat $zmaster 2>&1 | grep "Node does not exist"; do
> After i made this change i was able to execute rolling restart.
