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?
