[jira] [Created] (KAFKA-1679) JmxTool outputs nothing if any mbean attributes can't be retrieved

Ryan Berdeen created KAFKA-1679:
-----------------------------------

             Summary: JmxTool outputs nothing if any mbean attributes can't be retrieved
                 Key: KAFKA-1679
                 URL: https://issues.apache.org/jira/browse/KAFKA-1679
             Project: Kafka
          Issue Type: Bug
          Components: tools
            Reporter: Ryan Berdeen
            Priority: Minor


JmxTool counts the number of attributes for all MBeans and if the number of attributes retrieved does not equal this number, nothing is printed.

Several {{java.lang:type=MemoryPool}} MBeans have unsupported attributes (see HADOOP-8027, for example), so running JmxTool with no arguments fails to fetch these metrics and outputs nothing while continuing to run.
