--------------------------------------------
May be we should start considering automate rolling upgrade test?. In jenkins
we might be able to continuously grab 3.4 branch and perform rolling upgrade to
3.5 and verify that quorum come up

> I have a test in which I do a rolling restart of three ZooKeeper servers and
> it was failing from time to time.
> I ran the tests in a loop until the failure came out and it seems that at
> some point one of the servers is unable to join the enssemble formed by the
> other two.
