             Summary: Consider moving some tests before data load
                 Key: IMPALA-9689
                 URL: https://issues.apache.org/jira/browse/IMPALA-9689
             Project: IMPALA
          Issue Type: Improvement
          Components: Infrastructure
            Reporter: Csaba Ringhofer


Currently all tests run only after a successful data load, which is problematic because:
- broken data load leads to not executing the tests at all, so hides other issues than the one that data load bumps into first
- and data load is fairly complex, relying on functionality from several components (Impala/HMS/Hive server/HDFS/HBase/Kudu) so it can be broken easily, especially when we change the versions of dependencies

We could create a small test suite (e.g. "smoke") that runs before data load, or runs even if data load failed. Any test that creates its own tables and doesn't rely on functional/tpch/tpcds is suitable. Probably the most critical area is interoperability with Hive, e.g. creating table in Hive and reading it with Impala.
