I dont't want to stop cluster during upgrade, so my steps are: 1) on standby NN: hadoop-dameon.sh stop namenode 2) remove HA configuration in the conf 3) hadoop-daemon.sh start namenode -upgrade -clusterID test-cluster but Exception in the NN log, so how to upgrade and don't stop the whole cluster. Thanks. org.apache.hadoop.hdfs.server.common.InconsistentFSStateException: Directory /hdfs/name is in an inconsistent state: previous fs state should not exist during upgrade.
