--------------------------------------
Summary: Fix pytest ResourceWarnings
Key: IMPALA-14776
URL: https://issues.apache.org/jira/browse/IMPALA-14776
Project: IMPALA
Issue Type: Task
Components: Infrastructure, Test
Affects Versions: Impala 5.0.0
Reporter: Joe McDonnell
After switching to pytest 6.2.5, it now outputs information about leaked
resources (sockets, open files, thread pools):
{noformat}

authorization/test_ranger.py::TestRangerIndependent::test_grant_revoke_with_role["table_format:
text/none" | "protocol: hs2" | "exec_option: {'abort_on_error': 1,
'batch_size': 0, 'disable_codegen': False, 'disable_codegen_rows_threshold': 0,
'exec_single_node_rows_threshold': 0, 'num_nodes': 0, 'test_replan': 1}"]

/data0/jenkins/workspace/impala-cdw-master-staging-core-asan/repos/Impala/tests/common/impala_test_suite.py:951:
ResourceWarning: unclosed <socket.socket fd=47, family=AddressFamily.AF_INET,
type=SocketKind.SOCK_STREAM, proto=0, laddr=('127.0.0.1', 44380),
raddr=('127.0.0.1', 21050)>{noformat}
We should fix these warnings. In particular, tests that don't clean up clients
can cause there to be orphaned HS2 sessions that trigger
TestValidateMetrics.test_metrics_are_zero().
