load_nested.py should be enhanced to work against a kerberized+SSL Impala. load_nested.py uses the "Cluster" abstraction hierarchy in tests.comparison.cluster and the connection hierarchy in tests.comparison.db_connection. The patch will involve supporting SSL and bitrotted Kerberos test code in these abstractions.
Testing the patch should involve both loading of nested data and regression testing data load and the following regression tests, which are needed because they also use the "Cluster" abstraction hierarchy:
- full data load
- data load with snapshot
- loading of random data into Impala
- copying data from Impala to PostgreSQL
- stress test run (smoke)
- query generator run (smoke)
