> Currently ObserverReadProxyProvider uses {{HAServiceProtocol#getServiceStatus}} to get the status of each NN. However {{HAServiceProtocol}} does not leverage delegation token. So when running an application on YARN and when YARN node manager makes this call getServiceStatus, token authentication will fail, causing the application to fail.
