Our CI has been super flaky lately: it seems rare that a PR is able to pass without a few retries. In an effort to try to help I added a new label "Flaky tests" and tagged all the open issues that look related to flaky tests. I also closed a few that have been open for a long time and I don't recall seeing in a while. They are all here:
https://github.com/apache/incubator-druid/labels/Flaky%20test In a few cases I edited the titles so they all have the specific test case that failed (the class and method). I think it helps to have one issue per method, that way we can track them separately. Non-scientifically I seem to be noticing these four often these days: 1) https://github.com/apache/incubator-druid/issues/6296 2) https://github.com/apache/incubator-druid/issues/2373 3) https://github.com/apache/incubator-druid/issues/6311 4) https://github.com/apache/incubator-druid/issues/6312 Please, if we can, let's spend some time looking into what is going on with these tests. We will thank ourselves when it makes PR flow smoother!
