Subject [jira] [Created] (HADOOP-7358) Improve log levels when exceptions caught in RPC handler
Date Fri, 03 Jun 2011 21:45:47 GMT
Improve log levels when exceptions caught in RPC handler

                 Key: HADOOP-7358
                 URL: https://issues.apache.org/jira/browse/HADOOP-7358
             Project: Hadoop Common
          Issue Type: Improvement
          Components: ipc
    Affects Versions: 0.22.0
            Reporter: Todd Lipcon
            Priority: Minor
             Fix For: 0.22.0

When a server implementation throws an exception handling an RPC, the Handler thread catches
it and logs it before responding with the exception over the IPC channel. This is currently
done at INFO level.

I'd like to propose that, if the exception is an unchecked exception, it should be logged
at WARN level instead. This can help alert operators when they might be hitting some kind
of bug.
