Mingliang Liu updated HADOOP-12417:
-----------------------------------
Attachment: HADOOP-12417.000.patch
When creating jetty sever, the v0 patch always binds port *0* which gives us an
ephemeral port, instead of searching a free port before starting jetty.
In {{getJettyURL()}} methods, we should use {{connector.getLocalPort()}} after
the jetty starts.

> The {{TestWebDelegationToken}} failed on Jenkins with port in use. It looks
> like the code searches for a free port and then starts jetty, but maybe
> there's enough of a race condition between port location and jetty.start to
> cause intermittent failures.
