> Currently, we detect query hangs in tests by using execute_async() and wait_for_finished_timeout() of BeeswaxConnection together.
> E.g. [https://github.com/apache/impala/blob/3.3.0/tests/authorization/test_grant_revoke.py#L334-L335]
> {code:python}
>         handle = self.client.execute_async("invalidate metadata")
>         assert self.client.wait_for_finished_timeout(handle, timeout=60)
> {code}
> However, execute_async() won't return if the DDL is in CREATED state which is usually when DDL hangs. See the implementation of query() interface for Beeswax protocol: https://github.com/apache/impala/blob/3.3.0/be/src/service/impala-beeswax-server.cc#L52
> So wait_for_finished_timeout() don't run and the test is stuck in execute_async().
> We need to find a elegant way to detect DDL hangs and cancel the DDLs in CREATED state.
