             Summary: LLAP: LlapBaseInputFormat.getSplits(..., 0) should use LIMIT 0 query
                 Key: HIVE-21687
                 URL: https://issues.apache.org/jira/browse/HIVE-21687
             Project: Hive
          Issue Type: Bug
            Reporter: Gopal V


The 0 split query is useful in ensuring that the user has access to the tables and getting the result schema.

There's a fast-path for Tableau for "LIMIT 0" queries which can be used for this without touching the get_splits UDTF.
