Subject Re: submission w/classpath without
Date Fri, 23 Jan 2015 23:19:57 GMT
You have all the jars your app needs on both the servers and the client (as
opposed to wanting Yarn to distribute them)?  Then
yarn.application.classpath should be what you need.  It looks like
/etc/hadoop/conf,/some/lib/dir/*,/some/other/lib/dir/* etc.  Is that what
you're trying?
