Tsuyoshi OZAWA commented on YARN-2075:
--------------------------------------
I could reproduce this problem on both trunk and branch-2 and the patch works
well both of them on my local. [~mitdesai], can you tell us what command did
you run? I ran {{mvn clean test -Dtest=TestRMAdminCLI}} with the patch and it
works well.
