For example, rpc latency of Standby is very long > when Standby is catching up editlog. We may misunderstand the state of HDFS. > Using different metrics for Active and standby can help us obtain more > precise metric data. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
