-----------------------------------

             Summary: Run flaky test job more often
                 Key: HBASE-27425
                 URL: https://issues.apache.org/jira/browse/HBASE-27425
             Project: HBase
          Issue Type: Task
          Components: test
            Reporter: Sean Busbey
         Attachments: ci-hbase-hbase-flaky-test-master-time-png.png, ci-hbase-hbase-load-chart-long.png

We currently run the flaky tests once per 4 hours and keep a backlog of 50 runs. That means it takes a perfect test a bit over 8 days to get back out of being penalized.

we regularly are leaving a bunch of executors idle (see attached PNG) and I think we should run the tests more often.

we use an executor per branch for a flaky test run. the duration depends on the specific tests that are flagged, but it has a timeout of 2 hours.

as an example the master branch tests currently take < 30 minutes (see other attached PNG).
