             Summary: Enable Unit test - TestDruidRecordWriter.testWrite
                 Key: HIVE-16752
                 URL: https://issues.apache.org/jira/browse/HIVE-16752
             Project: Hive
          Issue Type: Bug
          Components: Druid integration
            Reporter: Nishant Bangarwa


After the changes done in https://issues.apache.org/jira/browse/HIVE-16474 the test is failing due to loading of guava classes from hive-exec jar. 
this is because the hive-exec jar is a shaded jar which contains all the dependencies. 
For details see - https://github.com/apache/hive/blob/master/ql/pom.xml#L820

"The way shade was configured since 0.13, is to override the default jar for ql module with the shaded one but keep the same name."

So when mvn resolves the jar when running the unit test, it sees the shaded jar which has guava also. 
To resolve this, there are two ways i could find - 
1) Tweak the order of dependencies in druid 
2) Somehow add a dependency in druid-handler for non-shaded jar, but since it has been already overridden, not sure how to do it. 
3) Use a different namespace for guava classes in hive-exec jar.
