Duo Zhang commented on HBASE-17081:
-----------------------------------
Busy these days so I do not have much time to help debugging the bugs directly.
In TestAsyncGetMultiThread, we will put 1000 rows to a table with 9 regions.
And then use several background threads to get the values and do some split and
move works. The failure is NPE when getting from a Result object which means
the row is missing so I think the problem maybe the flush when splitting or
moving. Hope this could help.
Thanks.

> Part of CompactingMemStore's memory is held by an active segment, and another
> part is divided between immutable segments in the compacting pipeline. Upon
> flush-to-disk request we want to flush all of it to disk, in contrast to
> flushing only tail of the compacting pipeline.
