ramkrishna.s.vasudevan updated HBASE-18442:
-------------------------------------------
Attachment: HBASE-18442_1.patch
Patch for trunk. Creates the BBs parallely. I tried moving the adding to
reclaimedChunks in the main thread and having it as in the current way of
patch. Did not observe significant difference. If it needs to be moved to the
main thread after waiting for the Future to get completed I can make suitable
changes to the patch.
