Method Calls
I am looking for the various method calls (entry points) in the inter tier
communication.
When the client submits a job for map-reduce, what is the sequence of calls
started, e.g Node Manager to Resource Manager or Container to App Master.
How is the App Master Child JVM spawned etc.
Does any one have a high level call flow / sequence diagram?
Thanks,
Rajesh

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
