Amar Kamat commented on HADOOP-2344:
------------------------------------
Changes made to the patch other than the javadoc changes
* logging some of the exceptions in {{ShellCommand}} and throwing the main/imp
ones.
* closing the streams explicitly.
* ignoring the error of {{df -k}} since exit code provides the required error
information
