------------------------------------
Summary: Replica region needs to do check if primary region exists
in hdfs during createRegionOnFileSystem().
Key: HBASE-24552
URL: https://issues.apache.org/jira/browse/HBASE-24552
Project: HBase
Issue Type: Bug
Components: read replicas
Affects Versions: 2.3.0
Reporter: Huaxiang Sun
Assignee: Huaxiang Sun
When a replica is opened, it does not check if region dir exists and if
.regionInfo exists in the directory, region server will online this replica
region even the primary region does not exist.
It needs to do better to do more checks and fails region open if the check does
not pass.
Maybe we can do this check in master, will see.
