> client fails forever when namenode ipaddr changed

> Key: HADOOP-17068
> URL: https://issues.apache.org/jira/browse/HADOOP-17068
> Project: Hadoop Common
> Issue Type: Bug
> Components: hdfs-client
> Reporter: Sean Chow
> Assignee: Sean Chow
> Priority: Major
> Attachments: HADOOP-17068.001.patch, HDFS-15390.01.patch

>
> For machine replacement, I replace my standby namenode with a new ipaddr and
> keep the same hostname. Also update the client's hosts to make it resolve
> correctly
> When I try to run failover to transite the new namenode(let's say nn2), the
> client will fail to read or write forever until it's restarted.
> That make yarn nodemanager in sick state. Even the new tasks will encounter
> this exception too. Until all nodemanager restart.
