Thomas Martens updated HBASE-18471:
-----------------------------------
Description:
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.
