ramkrishna.s.vasudevan updated HBASE-18649:
-------------------------------------------
Attachment: HBASE-18649_master_2.patch
An updated patch. All test cases passes hbase-backup. Key thing to note is that
a new Cell type called ExtendedCellWrapper(better name needed) in the
hbase-mapreduce package. It wraps all the cells in the mappers/reducers so that
the downstream code can safely work with ExtendedCell/Cells.
And other main thing is that the output value class should be an implementation
rather than an interface.

Thanks for the review. For the new BBUtil API since it is a write to DataOutput
there is no need to return an int I think. If you strongly feel otherwise I can
add one.
