> The qualifier of a deleted row (with keep deleted cells true) re-appears 
> after re-inserting the same row multiple times (with different timestamp) 
> with an empty qualifier.
> Scenario:
> # Put row with family and qualifier (timestamp 1).
> # Delete entire row (timestamp 2).
> # Put same row again with family without qualifier (timestamp 3).
> A scan (latest version) returns the row with family without qualifier, 
> version 3 (which is correct).
> # Put the same row again with family without qualifier (timestamp 4).
> A scan (latest version) returns multiple rows:
> * the row with family without qualifier, version 4 (which is correct).
> * the row with family with qualifier, version 1 (which is wrong).
> There is a test scenario attached.
> output:
> <LOG> 13:42:53,952 [main] client.HBaseAdmin - Started disable of test_dml
> <LOG> 13:42:55,801 [main] client.HBaseAdmin - Disabled test_dml
