stack commented on HBASE-20893:
-------------------------------
Here is an addendum that changes split and merge to just reopen regions if
recovered.edits found rather than try and do rollback (rollback doesn't work).
I need to check the merge case still (The split test gives a nice loud and
clear message that this addresses the CODE-BUG issue when splitting but having
harder time w/ the merge test). I also want to do some edit logging to make it
clear what is going on in here.... Will be back. Let me try this patch against
hadoopqa in meantime.
