Handle ClassCastException on AuthenticationException in LoadBalancingKMSClientProvider

    Details

      Description

      An Oozie job with a single shell action fails (may not be important, but if you needs the exact details I can provide them) with an error message coming from NodeManager:

      2016-05-10 11:10:14,290 ERROR org.apache.hadoop.yarn.YarnUncaughtExceptionHandler: Thread Thread[LogAggregationService #652,5,main] threw an Exception.
      java.lang.ClassCastException: org.apache.hadoop.security.authentication.client.AuthenticationException cannot be cast to java.security.GeneralSecurityException

      The unsafe cast is here:

      Because of this ClassCastException:

      • an uncaught exception is raised
      • we do not see the exact "caused by" exception/message
      • the oozie job fails
      • YARN logs are not reported/saved
