Description of problem: Currently whenever the rhs-hadoop-install script doesn't handle cleanup. So suppose a user runs the script and encounters an error (eg. ntp failure), the user will have to manually cleanup the setup (like brick mount, /etc/fstab entries ) before re-running the script.
Version-Release number of selected component (if applicable): 1_34-1.el6rhs
How reproducible: Always
Actual results: Script doesn't handle cleanup or rollback of operations from the previous run.
Expected results: Script should be capable to handling the cleanup. It is a tedious task to cleanup all the host machines.
The user does not have to undo the steps done by any of the scripts when an error is detected. The scripts are designed to be idempotent. However, there is a script named bin./cleanup.sh that will do most of the necessary clean up if that is desired.
