The mini stress has been prone to hangs in the past due to test bugs.

I'd recommend dumping the impala-server metrics and checking whether
the impala.thrift-server.beeswax-frontend.connections-in-use
is close to 64.
Then look at how many queries are actually still in flight. If there are
fewer than 64 queries in flight, then it's probably a test bug (because the
tests did not yet close their connections despite being done).
