Subject How a job works in YARN/Map Reduce
Date Wed, 06 Apr 2016 10:06:02 GMT
Hi All,

I am learning Hadoop- Yarn.

1,How a job works in YARN/Map Reduce? like navigation path.

Please check my understanding is right?


When the application  or job or client starts,client communicate with Name
node.
the application manager started on node ( data node  ), Application manager
 communicates with Resource manager ( on name node ) to get  resource.
The resource are assigned to container.The job runs on Container which is
JVM.


2,What is container?


Thanks & Regards,
Vinodh.N
