Jean-Daniel Cryans updated HBASE-7826:
--------------------------------------

    Attachment: HBASE-7826.patch

Shivendra, I think the patch you attached wasn't finished because the tests you added weren't
passing.

In any case, I fixed them and added another one that really exercises the sorting functionality.

> Hbase natively stores columns sorted based on the column qualifier. A scan is guaranteed
to return sorted columns. The Java API works fine but the Thrift API is broken. Hbase uses
TreeMap that ensures that sort order is maintained. However Hbase thrift specification uses
a simple Map to store the data. A map, since it is unordered doesn't result in columns being
returned in a sort order that is consistent with their storage in Hbase.
