Jason Lowe commented on YARN-5859:
----------------------------------
Thanks for the patch! I noticed there are other rather low timeouts in these
tests that weren't updated like these, and I assume they too could also fail if
the test machine hiccups.
{code}
// Resource Localization should fail and state is modified accordingly.
// Also Local should be release on the LocalizedResource.
Assert
.assertTrue(waitForResourceState(lr, rls, req,
LocalResourceVisibility.PRIVATE, user, appId, ResourceState.FAILED,
200));
[...]
// Now waiting for resource download to start. Here actual will not start
// Only the resources will be populated into pending list.
Assert
.assertTrue(waitForPrivateDownloadToStart(rls, localizerId1, 2, 500));
[...]
// Waiting for download to start. This should return false as new download
// will not start
Assert.assertFalse(waitForPublicDownloadToStart(spyService, 2, 100));
[...]
// Waiting for download to start. This should return false as new download
// will not start
Assert.assertFalse(waitForPublicDownloadToStart(spyService, 1, 100));
