    Description

      In several failure scenarios it would be very handy to have an option to quiesce the JobTracker.

      Recently, we saw a case where the NameNode had to be rebooted at a customer due to a random hardware failure - in such a case it would have been nice to not lose jobs by quiescing the JobTracker.
