Subject issue with defaut yarn.application.classpath value from yarn-default.xml for hadoop-2.3.0
Date Mon, 17 Mar 2014 21:38:00 GMT
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
