Josh Elser updated HBASE-26656:
-------------------------------
Hadoop Flags: Reviewed
Release Note: This tool will read hbase:meta and report any regions whose
rowkey and cell value differ in their encoded region name. HBASE-23328
illustrates a problem for read-replica enabled tables in which the encoded
region name (the MD5 hash) does not match between the rowkey and the value.
This problem is generally harmless for normal operation, but can break other
HBCK2 tools.
Resolution: Fixed
Status: Resolved (was: Patch Available)
Thanks for your reviews, Peter.

> URL: https://issues.apache.org/jira/browse/HBASE-26656
> Project: HBase

>
> HBASE-23328 describes a problem in which the serialized RegionInfo in the
> value of hbase:meta cells have an encoded regionname which doesn't match the
> encoded region name in the rowkey for that cell.
> This problem is normally harmless as assignment only consults the rowkey to
> get the encoded region name. However, this problem does break other HBCK2
> tooling, like {{{}extraRegionsInMeta{}}}.
> Rather than try to update each tool to account for when this problem may be
> present, create a new tool which an operator can run to correct meta and then
> use any subsequent tools as originally intended.
