Subject [jira] [Commented] (YARN-702) minicluster classpath construction requires user to set yarn.is.minicluster in the job conf
Date Mon, 20 May 2013 18:11:17 GMT

    [ https://issues.apache.org/jira/browse/YARN-702?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13662227#comment-13662227

Siddharth Seth commented on YARN-702:
-------------------------------------

When using the MiniCluster, users should be using the configuration object setup by the MiniCluster
(This includes the RM address as well), which exposes a method for just this. I don't think
this should leak into the NodeManager.

> YARN-129 improved classpath construction for miniclusters by, when yarn.is.minicluster
is set, adding the current JVM's classpath to the ContainerLaunchContext for the MR AM and
tasks.  An issue with this is that it requires the user to set yarn.is.minicluster on the
mapreduce side in the job conf, if they are not copying to RM conf into the jobconf.
> I think it would be better to bypass the ContainerLaunchContext and instead have the
nodemanager check the property, and if it is true, do the classpath additions there.
