Kihwal Lee created HDFS-4890: -------------------------------- Summary: Stop generating/sending datanode work in standby mode Key: HDFS-4890 URL: https://issues.apache.org/jira/browse/HDFS-4890 Project: Hadoop HDFS Issue Type: Bug Components: ha, namenode Affects Versions: 2.1.0-beta Reporter: Kihwal Lee
If NN comes up in standby and stays that way, repl queues are empty so no work is generated even though ReplicationMonitor is running. But if an ANN transitions to standby, more work can be generated and sent. Also any remaining work will be sent to datanodes. Current code drains existing work and stops generating new work in safe mode. HDFS-4832 will make it immediately stop in safe mode. Same can be done for standby. This change was also suggested in HDFS-3744. -- This message is automatically generated by JIRA.
