Chen Liang updated HDFS-14035:
------------------------------
Description: 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. (was: Currently ObserverReadProxyProvider uses
{{HAServiceProtocol#getServiceStatus}} to get the status of each NN.
{{HAServiceProtocol}} does not leverage delegation token. So when YARN node
manager makes this call, token authentication will fail, causing the
application to fail.)
