[jira] [Updated] (HADOOP-12417) TestWebDelegationToken failing with port in use

     [ https://issues.apache.org/jira/browse/HADOOP-12417?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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.
