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.) > NN status discovery does not leverage delegation token > ------------------------------------------------------ > > Key: HDFS-14035 > URL: https://issues.apache.org/jira/browse/HDFS-14035 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Chen Liang > Assignee: Chen Liang > Priority: Major > > Currently ObserverReadProxyProvider uses > {{HAServiceProtocol#getServiceStatus}} to get the status of each NN.
