-------------------------------------
Can try something like this :
{code:java}
@Override // HAServiceProtocol
public synchronized void transitionToStandby(StateChangeRequestInfo req)
throws ServiceFailedException, AccessControlException, IOException {
checkNNStartup();
if (nn.getState() == NameNode.OBSERVER_STATE.toString()
&& req.getSource() == RequestSource.REQUEST_BY_ZKFC) {
// Throw Some Exception....
}
nn.checkHaStateChange(req);
nn.transitionToStandby();
}
{code}
