-------------------------------------------
Summary: Refactor TestHDFSIntegration
Key: SENTRY-1429
URL: https://issues.apache.org/jira/browse/SENTRY-1429
Project: Sentry
Issue Type: Test
Reporter: Sravya Tirukkovalur
There are a few problems with this test that would be good to fix:
1. NN pulls the Sentry acls periodically, which means tests cannot verify acls
as soon as it sets up the required privileges. This requires having sleeps in
the test but it leads to some flakyness. We need to make sure we are actually
sleeping after setting the permissions and before veryfing. Or explore other
options to make this robust.
2. We need to make the tests more granular. There is a bunch of stuff happening
in a single test, so it is hard to pinpoint why a test failed without looking
at the stacktrace and debugging further.
3. Fix inter test dependencies if any. I see that some tests fail if run alone,
but fail when the entire test class is run, so there might be some depedencies
which we need to clean up.
4. Make these tests runnable on real cluster. So that we can catch any
integration and configuration issues.
