-----------------------------
Summary: Enhance znode parent validation when add_peer
Key: HBASE-25700
URL: https://issues.apache.org/jira/browse/HBASE-25700
Project: HBase
Issue Type: Bug
Components: Replication
Affects Versions: 2.4.2, 2.2.3
Reporter: mokai
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.
