Junping Du updated HDFS-7388: ----------------------------- Target Version/s: (was: 2.8.0) > Improve the log for HA failover > ------------------------------- > > Key: HDFS-7388 > URL: https://issues.apache.org/jira/browse/HDFS-7388 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: ha > Reporter: Jing Zhao > Assignee: Jing Zhao > > Currently to debug an issue during the NN HA failover (with automatic > failover setup), we usually need to check log from all the NN and ZKFC > daemons to figure out what triggered the failover. Possible reasons include > NN health issue, connection issues between zkfc and NN, connection issues > between zkfc and ZK, and manual op started by admin. It will be helpful to > improve the log in NN and ZKFC and add more information to make the debug > easier. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
