> HBASE-13811 and HBASE-13853 fixed an issue with WAL edit filtering.
> The root cause this time seems to be different. It is due to procedure based
> flush interrupting the flush request in case the procedure is cancelled from
> an exception elsewhere. This leaves the memstore snapshot intact without
> aborting the server. The next flush, then flushes the previous memstore with
> the current seqId (as opposed to seqId from the memstore snapshot). This
> creates an hfile with larger seqId than what its contents are. Previous
> behavior in 0.98 and 1.0 (I believe) is that after flush prepare and
> interruption / exception will cause RS abort.
