---------------------------------
Summary: 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
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.
