Commit 47dbfde0b2cabd14452f18527e954aec5891224c in impala's branch
refs/heads/master from Andrew Sherman

IMPALA-10249: Fix the flaky TestImpalaShell.test_queries_closed test.
This test for IMPALA-897 is testing that queries run by Impala Shell
from a script file are closed correctly. This is tested by an assertion
that there is one in-flight query during execution of a script
containing several queries. The test then closes the shell and checks
that there are no in-flight queries. This is the assertion which failed.
Change this assertion to instead wait for the number of in-flight
queries to be zero. This avoids whatever race was causing the flakiness.

> Project: IMPALA
> Issue Type: Bug
> Components: Clients
> Affects Versions: Impala 1.3
> Reporter: Lenni Kuff
> Assignee: Lenni Kuff
> Priority: Blocker
> Labels: shell
> Fix For: Impala 1.3
>
>
> For example, if a script like this is run:
> {code}
> select 1;
> select 1;
> select 1;
> select 1;
> select 1;
> select sleep(30000);
> {code}
> The queries are not actually closed until the session disconnects. This
> causes major problems with admission control because queries start to get
> rejected because they are still in-flight.
