Attachment: HBASE-15325-v9.patch
v8 missed tests on batching. Upload v9.
v9 only fix cell missing issue, still regards setBatch as allowPartial. The
patch v7 fix cell missing and semantic of setBatch both and it is the laster
version on review board.
> ResultScanner allowing partial result will miss the rest of the row if the
> region is moved between two rpc requests

> HBASE-11544 allow scan rpc return partial of a row to reduce memory usage for
> one rpc request. And client can setAllowPartial or setBatch to get several
> cells in a row instead of the whole row.
> However, the status of the scanner is saved on server and we need this to get
> the next part if there is a partial result before. If we move the region to
> another RS, client will get a NotServingRegionException and open a new
> scanner to the new RS which will be regarded as a new scan from the end of
> this row. So the rest cells of the row of last result will be missing.
