Anastasia Braginsky commented on HBASE-17081:
---------------------------------------------
Because CompositeSnapshot is now "on" by default, all the previous tests are
actually now working with CompositeSnapshot and testing it. However, because
the QA was complaining, I added a test working with previous way of snapshot,
meaning flushing only the tail of the compacting pipeline to the disk. The
updated patch is attached (V15).
> Flush the entire CompactingMemStore content to disk

> 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.
