[jira] [Created] (HDFS-14269) [SBN read] Observer node switches back to Standby after restart

Wei-Chiu Chuang created HDFS-14269:
--------------------------------------

             Summary: [SBN read] Observer node switches back to Standby after restart
                 Key: HDFS-14269
                 URL: https://issues.apache.org/jira/browse/HDFS-14269
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: namenode
    Affects Versions: 3.3.0
            Reporter: Wei-Chiu Chuang


The Observer state is not persistent. Once it restarts it becomes Standby node again. Since it does not participate in NameNode failover for now, should we assume an Observer node is always an Observer node? This state should be persisted somewhere, like in Zookeeper.

CC: [~csun] [~shv]. Like to get inputs from you. Have you discussed this before?
