Subject [jira] [Commented] (YARN-3528) Tests with 12345 as hard-coded port break jenkins
Date Fri, 24 Jul 2015 04:12:05 GMT

    [ https://issues.apache.org/jira/browse/YARN-3528?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14639881#comment-14639881

Brahma Reddy Battula commented on YARN-3528:
--------------------------------------------

[~wheat9] Yes, will bind to '0' wherever applicable(Please check comment [here|https://issues.apache.org/jira/browse/YARN-3528?focusedCommentId=14567153&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14567153]
). but as [~rkanter] mentioned, In some places it looks like we set a config (e.g. NM address,,Recovery
enabled) and then some other code actually starts using the port based on the config. In that
case, I think we can do something like this to choose a dynamic port.

> A lot of the YARN tests have hard-coded the port 12345 for their services to come up
on.
> This makes it impossible to have scheduled or precommit tests to run consistently on
the ASF jenkins hosts. Instead the tests fail regularly and appear to get ignored completely.
> A quick grep of "12345" shows up many places in the test suite where this practise has
developed.
> * All {{BaseContainerManagerTest}} subclasses
> * {{TestNodeManagerShutdown}}
> * {{TestContainerManager}}
> + others
> This needs to be addressed through portscanning and dynamic port allocation. Please can
someone do this.
