-----------------------------------------------------------------

I have faced similar issues like this ---

Where due to hdfs issue few hbase blocks also got corrupted causing data loss.

 

But inconsistencies were there with
---------

ERROR: Region \{ meta =>, <Table>,1676456432901.009c618e1fb9f35737872e13f92306f7., hdfs => null, deployed => , replicaId => 0 } found in META, but not in HDFS or deployed on any region server.

-----------

 

Tried with extraRegionsInMeta --> nothing found

Checking through the hbase:meta scan found

table:state was missing Hence required removing from hbase:meta solved the issue.

 

Here I am very interested to see if we can clear all the fields from hbase:meta if hdfs path is not avaliable.

> Some times, we delete one table dir on hdfs, we need use hbck2 to fix region info in hbase:meta...
> but some times, we use hbase shell delete the table state uncarefully，just like execute:
> deleteall 'hbase:meta','t1,xxx' (it not prevented...)
> then the table state lose
> when we want to use extraRegionsInMeta to remove these unuseful regions in meta...but it failed,beacuse the table is not exist..
> I think we should support do extraRegionsInMeta when table not exists...or there are other method to fix it?
