Subject [jira] [Updated] (HBASE-7826) Improve Hbase Thrift v1 to return results in sorted order
Date Tue, 12 Feb 2013 02:15:12 GMT

]

Shivendra Pratap Singh updated HBASE-7826:
------------------------------------------

    Description: 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.  (was: Hbase
