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

2014-03-17 Thread REYANE OUKPEDJO 
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

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
