Sean Busbey resolved HBASE-21158.
---------------------------------
Resolution: Fixed
Hadoop Flags: Incompatible change
Release Note:
<!-- markdown -->
Scans that make use of `QualifierFilter` previously would erroneously return
both columns with an empty qualifier along with those that matched. After this
change that behavior has changed to only return those columns that match.
updated with release note and flagged it for a change in behavior.
> Empty qualifier cell is always returned when using QualifierFilter
