> Observed this in the testing with Phoenix. The test in Phoenix - MutableIndexFailureIT
deliberately fails the batchmutation call via the installed coprocessor. But the update is
not rolled back. That leaves the memstore inconsistent. In particular, I observed that getFlushableSize
is updated before the coprocessor was called but the update is not rolled back. When the region
is being closed at some later point, the assert introduced in HBASE-10514 in the HRegion.doClose()
causes the RegionServer to shutdown abnormally.
