[ https://issues.apache.org/jira/browse/HBASE-26199?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=17403176#comment-17403176 ] Anoop Sam John commented on HBASE-26199: These are due to bugs in 2.x initial versions. There a bunch of such bugs. These are around the CompactedHFilesDischarger feature added in 2.x. I dont have a list of jiras. We use 2.1.6 version where I believe all of these are fixed. These bugs cause some of the already compacted away files not to get deleted and when cluster is restarted, those came back to system. Well when these are HFiles for META table, this will cause regions from deleted tables and already split regions to come back. Pls try upgrade the HBase version (preferably 2.3.x) so that you wont see such issues at all.. > hbck2 should support remove deleted meta region > --- > > Key: HBASE-26199 > URL: https://issues.apache.org/jira/browse/HBASE-26199 > Project: HBase > Issue Type: Bug > Components: hbase-operator-tools, hbck2 >Reporter: mengqi >Priority: Major > > A large number of regions of deleted tables will enter rit when hbase2.x > restarts， and these region will also appear on hbck web page, we just delete > these region in meta table，and change active master。 > here is my request: [pull > request|https://github.com/apache/hbase-operator-tools/pull/81] -- This message was sent by Atlassian Jira (v8.3.4#803005)

Those region not only in deleted tables, but also in some normal tables, but
thoese regions already splited long time ago. I don't konw whether the split
procedure succ or not.

Thanks for giving more details on this. Any chance these regions were already
"in-transition" prior to table deletion? Whilst the hbck2 method proposed here
is very much useful, it would be important to try understand why this issue
happens in the first place. BTW, in which hbase version are you seeing this?

How have you deleted these tables? Did the table delete call succeed, or were there unassign procedure failures? What was these table states in meta?
