Joydeep Sen Sarma updated HIVE-1464:
------------------------------------
Attachment: 1464.1.patch
- skips loading source tables again and again for each test.
- clears state before a test by removing all tables other than the source
tables and reinitializing hiveconf
- some test results have changed because the previous results were incorrect.
they depended on the presence of tables from prior tests. once those tables are
cleared out - the test results change
- added a pre-execute hook for test runs to make sure that none of the source
tables are cleaned out.
Result: TestNegativeCliDriver is taking about:
- 7 min in current trunk
- 1.5 min with this patch
this includes compilation etc. as well i presume - so the actual speedup is
higher.
TestCliDriver is too long to do a comparative run.
> improve test query performance

>
> clientpositive/negative tests are extremely slow.
> one major problem seems to be that all the test warehouse tables are deleted
> and created/re-populated for each test. most of the times this is not
> required and if we can fix this the tests will run much faster.
