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

             Summary: ClassNotFoundException: org.apache.hadoop.yarn.server.api.DistributedSchedulingAMProtocol
when using hadoop-client-minicluster
                 Key: YARN-7673
                 URL: https://issues.apache.org/jira/browse/YARN-7673
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Jeff Zhang


I'd like to use hadoop-client-minicluster for hadoop downstream project, but I encounter the
following exception when starting hadoop minicluster.  And I check the hadoop-client-minicluster,
it indeed does not have this class. Is this something that is missing when packaging the published
jar ?
