[jira] [Created] (HADOOP-12028) Allow to set handler thread name when building IPC Server
Jeff Zhang created HADOOP-12028:

Summary: Allow to set handler thread name when building IPC Server
Key: HADOOP-12028
URL: https://issues.apache.org/jira/browse/HADOOP-12028
Project: Hadoop Common
Issue Type: Improvement
Affects Versions: 2.7.0
Reporter: Jeff Zhang
Currently IPC use the server port to differentiate it with other IPC server.
This is not very clear especially when port is randomly generated. It is better
to set the server name when building the server and use the server name as the
part of handler thread name
