------------------------------------
Summary: Fix Empty region in meta with read replica
Key: HBASE-24707
URL: https://issues.apache.org/jira/browse/HBASE-24707
Project: HBase
Issue Type: Improvement
Components: hbck2
Affects Versions: 2.3.0
Reporter: Huaxiang Sun
Assignee: Huaxiang Sun
Currently, there is a case in CatalogJanitor which checks if the default region
info is missing in metaRow, it is reporting it as EmptyRegionInfoList.
For read replica, this entry needs to be dealt with. In hbase-1, this was
caused by region server opens an orphan replica region. In hbase-2, it will not
happen since checks are added to defend this case. The hback2 fix is still
needed for upgrade. Issues could be brought into hbase-2 post upgrade, hbck2
needs to handle it.
