Anoop Sam John commented on HBASE-3093:
---------------------------------------

This test case is tested against 0.94 branch and it passed.!
May be issue with 89 branch alone? !!

> When calling Delete.deleteColumns to delete (all versions of) a column, the columns with
a qualifier that is alphabetical higher than the deleted column are deleted as well when the
cells have timestamp 0.
> When the cells have a timestamp higher than 0 this is not the case.
> The test case DeleteColumnsTest (tested against HBase 0.89.0-r1004203-3076) contains
a scenario showing this behaviour :
> - put values in 3 columns (A, B and C) of the same column family at timestamp 0.
> - delete all versions of column B (using Delete.deleteColumns() )
> - read columns A and C
> - result : for column A a result is given, for column C not (the alphabetical order is
in play here!)
