stack updated HBASE-1892:
-------------------------
Release Note: On region close, this change makes it so we don't wait on
compaction to complete with the close-region flag in place -- i.e. region is
offline while we wait on the compaction close -- and secondly, if the region
memstores are over a configurable limit, before closing, we'll run a
"pre-flush" to get the bulk of the memory flushed before we put the close flag
up.
