> Flushing canceled by coprocessor still leads to memstoreSize set down

> Affects Versions: 0.98.13, 1.0.2, 1.2.0, 1.1.1
> Reporter: Yerui Sun

>
> A Coprocessor override "public InternalScanner preFlush(final Store store,
> final InternalScanner scanner)" and return NULL when calling this method,
> will cancel flush request, leaving snapshot un-flushed, and no new storefile
> created. But the HRegion.internalFlushCache still set down memstoreSize to 0
> by totalFlushableSize.
> If there's no write requests anymore, the memstoreSize will remaining as 0,
> and no more flush quests will be processed because of the checking of
> memstoreSize.get() <=0 at the beginning of internalFlushCache.
> This issue may not cause data loss, but it will confuse coprocessor users. If
> we argree with this, I'll apply a patch later.
