Rajesh Balamohan commented on TEZ-2242:
---------------------------------------

+1. lgtm. 
- handleVertexStateUpdate(stateUpdate) in onVertexStarted() would be called, 
only when the child class calls registerForVertexStateUpdates(). This would not 
be invoked in normal codepath.

minor comment 
- It mighight not be necessary to synchronize onVertexStarted()? That might fix 
the findbugs issue as well.



> Refactor ShuffleVertexManager code
