---------------------------------------

             Summary: ProtobufRpcEngine.invoke() should use 
Exception.toString() over getMessage in logging/span events
                 Key: HADOOP-12051
                 URL: https://issues.apache.org/jira/browse/HADOOP-12051
             Project: Hadoop Common
          Issue Type: Bug
          Components: ipc
    Affects Versions: 2.7.0
            Reporter: Steve Loughran
            Priority: Minor


in {{ProtobufRpcEngine.invoke()}}, caught throwables have their {{getMessage()} 
included in the timeline events for the span. For some events (eg NPE) this 
will be null. it should be calling {{toString()}} instead
