------------------------------------
Labels: pull-request-available (was: )
> Updated addresses are still accessed using the old IP address
> -------------------------------------------------------------
>
> Key: HADOOP-18365
> URL: https://issues.apache.org/jira/browse/HADOOP-18365
> Project: Hadoop Common
> Issue Type: Improvement
> Components: common
> Environment: Demonstrated in a Kubernetes environment running Java 11.
> Reporter: Steve Vaughan
> Priority: Major
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h

> When the IPC Client recognizes that an IP address has changed, it updates the
> server field and logs a message:
> Address change detected. Old:
> journalnode-1.journalnode.hdfs.svc.cluster.local/10.1.0.178:8485 New:
> journalnode-1.journalnode.hdfs.svc.cluster.local/10.1.0.182:8485
> Although the change is detected, the client will continue to connect to the
> old IP address, resulting in repeated log messages. This is seen in managed
> environments when JournalNode syncing is enabled and a JournalNode is
> restarted, with the remaining nodes in the set repeatedly logging this
> message when syncing to the restarted JournalNode.
> The source of the problem is that the remoteId.address is not updated.
