Rohith Sharma K S commented on YARN-4614:
-----------------------------------------
thanks [~sunilg] for your analysis. It make sense to me. I verified the test
using debug point in eclipse, as you said that one extra node heartbeat kick
off scheduling and allocate a container which attempt goes to ALLOCATED state.
And also I verified test with patch using debug mode, test cases passes.
