---------------------------------------
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.
