Vinay Kumar Thota commented on MAPREDUCE-1713:
----------------------------------------------
- don't use intExp.printStackTrace();. Consider passing the Throwable to
LOG.warn invocation instead.
Done.
- stop() and stop(String confLocation) are defined in ClusterProcessManagement
interface. So, I'm kinda confused by your explanation
Yes,you are correct.But what I said is the stop() and start() methods are also
available in AbstractDamenonCluster. Those methods
implcitly calling the clusterManager.start() and clusterManager.stop().
> Utilities for system tests specific.
