> Key: HADOOP-12282

> Project: Hadoop Common
> Issue Type: Bug
> Components: ipc
> Reporter: zhouyingchao

>
> In a hadoop hdfs cluster, I changed the standby Namenode's ip address (the
> hostname is not changed and the routing tables are updated). After the
> change, the cluster is running as normal.
> However, I found that the debug message of datanode's IPC still prints the
> original ip address. By looking into the implementation, it turns out that
> the original address is used as the thread's name. I think the thread's name
> should be changed if the address change is detected.
