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

             Summary: webhcat jobs that need to access metastore fails in secure mode
                 Key: HIVE-5133
                 URL: https://issues.apache.org/jira/browse/HIVE-5133
             Project: Hive
          Issue Type: Bug
          Components: WebHCat
    Affects Versions: 0.11.0
            Reporter: Thejas M Nair
            Assignee: Thejas M Nair


Webhcat job submission requests result in the pig/hive/mr job being run from a map task that
it launches. In secure mode, for the pig/hive/mr job that is run to be authorized to perform
actions on metastore, it has to have the delegation tokens from the hive metastore.
In case of pig/MR job this is needed if hcatalog is being used in the script/job.
