stack commented on HBASE-4991:
------------------------------
bq. Are we going to enhance Merge by allowing to discard data belonging to one
of the regions ?
This feature looks to be adding online merge to me. I need clarification from
Mubarak that that is indeed the case. If so, this issue is mislabeled and the
patch needs redoing.
I was just suggesting that if you want to actually drop a regions data, you
could pass a flag to merge and it would not bother copying over the files from
old regions. That would be an option. This patch as is does not do that. It
seems to copy old region data into new regions. Was just a suggestion.
bq. How should we deal with various failure scenarios in the process of merging
?
Eh... in a manner which is resilient against failures, TBD. I don't get your
question Ted. Are you asking me or the Author of this patch?
