Tao Jie created HADOOP-12569: -------------------------------- Summary: ZKFC should stop namenode before itself quit in some circumstances Key: HADOOP-12569 URL: https://issues.apache.org/jira/browse/HADOOP-12569 Project: Hadoop Common Issue Type: Bug Components: ha Affects Versions: 2.6.0 Reporter: Tao Jie
We have met such a HA scenario: NN1(active) and zkfc1 on node1; NN2(standby) and zkfc2 on node2. 1,Stop network on node1, NN2 becomes active. On node2, zkfc2 kills itself since it cannot connect to zookeeper, but leaving NN1 still running. 2,Several minutes later, network on node1 recovers. NN1 is running but out of control. NN1 and NN2 both run as active nn. Maybe zkfc should stop nn before quit in such circumstances. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
