Subject [jira] [Updated] (HADOOP-10106) Incorrect thread name in RPC log messages
Date Mon, 16 Dec 2013 22:16:07 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-10106?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jing Zhao updated HADOOP-10106:
-------------------------------

       Resolution: Fixed
    Fix Version/s: 2.4.0
     Hadoop Flags: Reviewed
           Status: Resolved  (was: Patch Available)

I've committed this to trunk and branch-2. 

[~mingma], currently I could not add your name to the contributor list (got some error msg
in the jira system) so I could not assign this jira to you. I will try it again and update
the jira information later.

> INFO org.apache.hadoop.ipc.Server: IPC Server listener on 8020: readAndProcess from client
10.115.201.46 threw exception org.apache.hadoop.ipc.RpcServerException: Unknown out of band
call #-2147483647
> This is thrown by a reader thread, so the message should be like
> INFO org.apache.hadoop.ipc.Server: Socket Reader #1 for port 8020: readAndProcess from
client 10.115.201.46 threw exception org.apache.hadoop.ipc.RpcServerException: Unknown out

> Another example is Responder.processResponse, which can also be called by handler thread.
When that happend, the thread name should be the handler thread, not the responder thread.
