tomscut created HDFS-16547: ------------------------------ Summary: [SBN read] Namenode in safe mode should not be transfer to observer state Key: HDFS-16547 URL: https://issues.apache.org/jira/browse/HDFS-16547 Project: Hadoop HDFS Issue Type: Improvement Reporter: tomscut Assignee: tomscut
Currently, when a Namenode is in safemode(under starting or enter safemode manually), we can transfer this Namenode to Observer by command. This Observer node may receive many requests and then throw a SafemodeException, this causes unnecessary failover on the client. So Namenode in safe mode should not be transfer to observer state. -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
