stack commented on HBASE-12485:
-------------------------------
On first point, ok. Log as ERROR then?
On second, yeah, would be good if all 'special' files were in one place (hbck
is going to run into these sequence files one day -- smile)
> Maintain SeqId monotonically increasing

> We added FLUSH, REGION CLOSE events into WAL, for each those events the
> region SeqId is bumped.
> The issue comes from region close operation. Because when opening a region,
> we use flushed SeqId from store files while after store flush during region
> close we still write COMMIT_FLUSH, REGION_CLOSE events etc which respectively
> bump up SeqId. Therefore, the region opening SeqId is lower than it should
> be.
