> 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.
