Yarn Test Timeout

[Vijay Srinivasaraghavan]

Hello,
I am seeing a "timeout" issue for one of the Yarn test case 
(YarnSessionCapacitySchedulerITCase>YarnTestBase.checkClusterEmpty) and noticed 
similar references in FLINK-2213 (https://github.com/apache/flink/pull/1588)
I have tested in latest mater code. Is anyone seeing this issue?
RegardsVijay
