   I am facing the same issue.  A sample application to replicate this issue can be found:
   https://github.com/linkedin/datahub
   Of course, it is a big project so it would take some effort to understand it. 
   But if we just use one of its module: https://github.com/linkedin/datahub/tree/master/metadata-jobs/mce-consumer-job
   and run this module's jar file. I am seeing the same error reported.
