Josh Elser commented on HBASE-22144:
------------------------------------
Ugh, this doesn't come back to branch-2.0 or branch-2.1 due to HBASE-19008 and
HBASE-21129 never being backported to these branches. I'm not sure what the
lesser headache would be: making sure those changes don't break public API
guarantees or re-implementing this fix.

> It appears that MultiRowRangeFilter was never written to function with
> reverse scans. There is too much logic that operates with the assumption that
> we are always moving "forward" through increasing ranges. It needs to be
> rewritten to "traverse" forward or backward, given how the context of the
> scan being used.
