--------------------------------------

             Summary: Deleted qualifier re-appearing after multiple puts.
                 Key: HBASE-18471
                 URL: https://issues.apache.org/jira/browse/HBASE-18471
             Project: HBase
          Issue Type: Bug
          Components: Deletes, hbase, scan
    Affects Versions: 1.3.0
            Reporter: Thomas Martens


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).
