Robert Joseph Evans commented on STORM-2809: -------------------------------------------- So it appears to be something related to the AsyncLocallizer checking if a blob is fully downloaded as part of the periodic check to see if it has changed. When I comment out that part everything works fine, except if the files get deleted part way through the supervisor will not recover. I am not totally sure why this is the case, but I am going to try to dig into it. > Integration test is failing consistently and topologies sometimes fail to > start workers > --------------------------------------------------------------------------------------- > > Key: STORM-2809 > URL: https://issues.apache.org/jira/browse/STORM-2809 > Project: Apache Storm > Issue Type: Bug > Affects Versions: 2.0.0 > Reporter: Stig Rohde Døssing > Assignee: Robert Joseph Evans > Fix For: 2.0.0 > > > The integration test has been failing fairly consistently since > https://github.com/apache/storm/pull/2363. I tried running the test outside a > VM with a locally installed Storm setup, and it has failed every time for me. > Most runs seem to fail in ways that make it look like the integration test is > just flaky (e.g. tuple windows not matching the calculated window), but in at > least a few tests I saw the topology get submitted to Nimbus followed by > about 3 minutes of nothing happening. The workers never started and the > supervisor didn't seem aware of the scheduling. The only evidence that the > topology was submitted was in the Nimbus log. This still happens even if the > test topologies are killed with a timeout of 0, so there should be slots free > for the next test immediately. > I tried reverting https://github.com/apache/storm/pull/2363 and it seems to > make the integration test pass much more often. Over 5 runs there was still > an instance of a supervisor failing to start the workers, but the other 4 > passed. > We should try to fix whatever is causing the supervisor to fail to start > workers, and get the integration test more stable. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
