Re: issue with defaut yarn.application.classpath value from yarn-default.xml for hadoop-2.3.0

[Akira AJISAKA <aj...@oss.nttdata.co.jp>]

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.

Thanks,
Akira
