Last week I noticed that our CI ( https://builds.apache.org/job/Mesos-Buildbot) has been failing for some time (I've heard somewhere between 2 weeks and a month). It seems like none of us (including me of course) are paying much attention to the builds.apache.org emails. Hard to blame ourselves for filtering these emails and not paying much attention to the failures given the history of flaky tests.
However, I would like to point out that Alex Rukletsov has done a fantastic job over the last 4 months or so of trying to keep our CI in a sane state. He's been identifying, tracking, and keeping authors accountable of the flaky tests and there has been great progress. I would love it if we can reap the benefits of his (and others!) efforts simply by us keeping a closer eye on our CI. Thanks, MPark
