[HDFS-15281] ZKFC ignores dfs.namenode.rpc-bind-host and uses dfs.namenode.rpc-address to bind to host address

• Target Version/s: 2.9.3, 3.1.4, 3.2.2, 2.10.1
• Hadoop Flags: Reviewed

Release Note

ZKFC binds host address to "dfs.namenode.servicerpc-bind-host", if configured. Otherwise, it binds to "dfs.namenode.rpc-bind-host". If neither of those is configured, ZKFC binds itself to NameNode RPC server address (effectively "dfs.namenode.rpc-address").

Description

When ZKFC binds its RPC server to a hostname for listening, it uses the host value specified by dfs.namenode.rpc-address. It should instead use dfs.namenode.rpc-bind-host if that value has been set. If the value has not been set, then it can fall back on  dfs.namenode.rpc-address as it currently does.
