Subject Re: Method Calls

Hi,

I think you should take a look at yarn architecture blog series. I found
them useful when I started working on YARN (
http://hortonworks.com/blog/introducing-apache-hadoop-yarn/) This will give
you a very good picture about communication between different modules and
roles played by them.

Thanks,
Omkar Joshi
