wchevreuil commented on issue #456: HBASE-22631 assign failed may make gced parent region appear again URL: https://github.com/apache/hbase/pull/456#issuecomment-520468069 Thanks for the extra details, yuhuiyang. So the issue seems to be that this region was supposedly deleted already, as we could see the _GCRegionProcedure_ has completed **success** for that region, but then it comes back when a given RS crashes and an SCP is submitted to it. Is it possible to share this Master log file, together with the tempt20 RS log file, covering this period between "2019-06-26 10:40" and "2019-06-26 10:42"? I suspect this might be same issue as the one addressed in **HBASE-21843**, where RS holding meta crashes, then meta wal edits are skipped in the wal replay, which misses some recent updates to meta.
