[jira] Created: (HADOOP-592) NullPointerException in toString for RPC connection objects

NullPointerException in toString for RPC connection objects
-----------------------------------------------------------

                 Key: HADOOP-592
                 URL: http://issues.apache.org/jira/browse/HADOOP-592
             Project: Hadoop
          Issue Type: Bug
    Affects Versions: 0.7.0
            Reporter: Owen O'Malley
         Assigned To: Owen O'Malley
            Priority: Minor
             Fix For: 0.7.1


If the socket is closed when the log message is generated, the toString method gets a NullPointerException.

The exception is caught and logged, but happens often enough that administrators will worry about it. It also loses useful debugging information.

Owen O'Malley updated HADOOP-592:
---------------------------------

    Attachment: connection-null-ptr.patch

This patch grabs the inet address when the connection is formed so that we don't get a null pointer exception when trying to print it out after the connection is closed.
