Yu Li commented on HBASE-16195:
-------------------------------

bq. The hard limit is the blocking flush size which defaults to 4 times the 
flush size.
I agree that blockingFlushSize/chunkSize is a better default value, but I still 
think it's dangerous to have an unlimited queue here. :-)

bq. Both these jiras part of single bug. So any one backporting this has to 
take both.
Sorry I don't quite catch you on this sir. Even w/o limiting the chunk queue 
size, we still need to fix the part that chunk is put into queue when no pool 
specified, right? So user still need to backport both to thoroughly resolve the 
problem mentioned in HBASE-16193, I guess?

> Should not add chunk into chunkQueue if not using chunk pool in
