> ---------------------------------------------
>
> Key: HBASE-25700
> URL: https://issues.apache.org/jira/browse/HBASE-25700
> Project: HBase
> Issue Type: Improvement
> Components: Replication
> Affects Versions: 2.2.3, 2.4.2
> Reporter: mokai
> Assignee: mokai
> Priority: Minor
>
> If the znode parent end with empty string, add_peer command has no
> validation. It should be enhanced.
> Command example: add_peer '1', CLUSTER_KEY => "10.244.225.186:2181:/hbase ",
> STATE => "ENABLED"
> It causes enable_table_replication execute failed with folloing error.
