* kept in each MemStore's snapshot and wait for next flush attempt to continue on it. But when
* the next flush succeeds, the counter of total memstore size in HRegion is always deduced by
* the sum of current memstore sizes instead of snapshots left from previous failed flush. This
* calculation is problematic that almost every time there is failed flush, HRegion.memstoreSize
* gets reduced by a wrong value. If region flush could not proceed for a couple cycles, the size
* in current memstore could be much larger than the snapshot. It's likely to drift memstoreSize
* much smaller than expected. In extreme case, if the error accumulates to even bigger than
* HRegion's memstore size limit, any further flush is skipped because flush does not do anything
* if memstoreSize is not larger than 0."
