-----------------------------------------------
Thanks JD. I did realize that the patch unit test had a bug and fixed that, but
thanks for adding the check for testing the sorting functionality as well.
> Improve Hbase Thrift v1 to return results in sorted order

> 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.
