Anoop Sam John commented on HBASE-10844:
----------------------------------------
IMO it will be good to be consistent with the sync wal case. ie even if
WriteToWal is false, do not rollback with failures in post hooks. post means
the mutation is done.
> Coprocessor failure during batchmutation leaves the memstore datastructs in
> an inconsistent state

> 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.
