This is intentional.
See https://issues.apache.org/jira/browse/YARN-1138 for the detail.
If you want to use the default parameter for your application,
you should write the same parameter to config file or you can use
YarnConfiguration.DEFAULT_YARN_APPLICATION_CLASSPATH instead of
using yarn.application.classpath.

Hi,
I believe there is an issue with yarn-default.xml setting
of yarn.application.classpath on hadoop-2.3.0. This parameter's default
is not set and I have an application that fails because of that. Below
is part of the the content of yarn-default.xml which shows an empty
value of that parameter. When I checked the same file on hadoop-2.2.0, I
can see that a default value is set. Can anyone explain why this happens
? should I open a bug report? or was this intentional ?
Thanks
