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

             Summary: Cleanup unnecessary shaded libraries for job/coprocessor/jdbc/server
                 Key: KYLIN-2428
                 URL: https://issues.apache.org/jira/browse/KYLIN-2428
             Project: Kylin
          Issue Type: Improvement
          Components: General
    Affects Versions: v1.6.0
            Reporter: Billy Liu
            Assignee: Billy Liu


Kylin releases three libraries: kylin-coprocessor, kylin-jdbc, kylin-job and one web application: server. 
Currently, all libraries have shaded some used third party libraries into the package. For example, guava, curator, commons, kyro in kylin-job. The duplicate libraries in runtime classpath may have potential class loading conflicts and waste computing resource. We should leverage the hadoop provided libraries at runtime instead of the shaded one.
