Suraj Menon commented on HAMA-723:
----------------------------------

Work in progress here - https://github.com/ssmenon/hama/compare/apache:trunk...HAMA-723
The data could be sorted in SortedSpilledByteBuffer using SortOnSpilledBufferCallable.
TwoWayMergeCallable is used to merge records from 2 input ByteBuffer to an output buffer.
The remaining work is in progress, I shall update the code with some documentation.
