             Summary: rolling-restart.sh script unable to check expiration of master znode
                 Key: HBASE-7785
                 URL: https://issues.apache.org/jira/browse/HBASE-7785
             Project: HBase
          Issue Type: Bug
          Components: scripts
    Affects Versions: 0.94.4
         Environment: Linux CentOS release 5.8
            Reporter: Samir Ahmic


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.
