Change subject: IMPALA-5908: Allow SET to unset modified query options. ...................................................................... IMPALA-5908: Allow SET to unset modified query options. The query 'SET <option>=""' will now unset option, reverting it to its default state. This change became necessary with "SET" started returning an empty string for unset options which don't have a default. The test infrastructure (impala_test_suite.py) resets options to what it thinks is its defaults, and, when this broke, some ASAN builds started to fail, presumably due to a timing issue with how we re-use connections between tests. Testing: * Added a simple test that triggered this side-effect without this code. Specifically, "impala-python infra/python/env/bin/py.test tests/metadata/test_set.py -s" with the modified set.test triggers. * Added cases to query-options-test to check behavior for both defaulted and non-defaulted values. * Ran an ASAN build where this was triggering previously.
