Lars Hofhansl commented on HBASE-8847:
--------------------------------------
+1 on second patch. This is a nice improvement.
After this "baked" some in trunk, we should probably port over to 0.94/0.95.
> Filter.transform() always applies unconditionally, even when combined in a
> FilterList

> FilterList.transform() applies all transformation from all filters

> This leads to surprising results, eg. with combinations such as
