Huaxiang Sun updated HBASE-27251:
---------------------------------
Release Note:
Before upgrading HBase cluster to 2.5.0, it is strongly recommended to upgrade
the cluster to HBase-2.4.14 or later first. This is to guarantee a smooth
rollback in case. Otherwise, it may run into HBASE-27251.
Resolution: Fixed
Status: Resolved (was: Patch Available)
> Rolling back from 2.5.0-SNAPSHOT to 2.4.13 fails due to `File does not exist:
> /hbase/MasterData/data/master/store/.initialized/.regioninfo`
