{code}
The Region Server Name is used as memberName, but since the snapshot manger is
initialized before the RS receives the server name used by the master, the
zkprocedure will use the wrong name (0.0.0.0).
This will case the snapshot to fail with a TimeoutException since the master
will not receive the expected RS
