Minho Kim resolved HAMA-963.
----------------------------
Resolution: Fixed
This problem occurs since partition id is allocated to containerId which is
allocated by YARN. ContainerId of the worker tasks begin with 2 because the
first containerId is allocated to ApplicationMaster. It means that splits'
array overflow occurs when you run Hama application on YARN.
I fixed it!
Thanks.
