Tim Armstrong updated IMPALA-8952:
----------------------------------
    Component/s: Infrastructure

> test_failpoints does not check that queries actually fail
> ---------------------------------------------------------
>
>                 Key: IMPALA-8952
>                 URL: https://issues.apache.org/jira/browse/IMPALA-8952
>             Project: IMPALA
>          Issue Type: Test
>          Components: Infrastructure
>            Reporter: Sahil Takiar
>            Priority: Major
>
> While adding some additional failpoint tests in IMPALA-8934, [~kwho] pointed 
> out there is a bug in the pattern below (copied from 
> {{test_failpoints.py::TestFailpoints::__execute_fail_action}}):
> {code}
>     try:
>       result = self.execute_query(query, vector.get_value('exec_option'),
>                          table_format=vector.get_value('table_format'))
>       assert 'Expected Failure'
>     except ImpalaBeeswaxException as e:
>       LOG.debug(e)
> {code}
> The assert always returns true, so the test does not truly validate that the 
> queries are actually failing. After fixing this bug, about a third of the 
> tests fail.
