Subject [jira] [Commented] (YARN-2304) TestRMWebServices* fails intermittently
Date Fri, 18 Jul 2014 16:05:06 GMT

    [ https://issues.apache.org/jira/browse/YARN-2304?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14066469#comment-14066469
] 

Tsuyoshi OZAWA commented on YARN-2304:
--------------------------------------

IIUC, the test failure is caused by JerseyTest. JerseyTest's constructor -> getContainer()
-> getBaseURI always returns the result of UriBuilder.fromUri("http://localhost/").port(getPort(9998)).build().
If the another test jobs are running at the same time, some of them fail to bind port and
tests fail as a result.

{code}
    public JerseyTest(AppDescriptor ad) throws TestContainerException {
        this.tc = getContainer(ad, getTestContainerFactory());
        this.client = getClient(tc, ad);
    }

    /**
     * Returns the base URI of the application.
     * @return The base URI of the application
     */
    protected URI getBaseURI() {
        return UriBuilder.fromUri("http://localhost/")
                .port(getPort(9998)).build();
    }
{code}
