             Summary: Extend the YARN resource model for easier resource-type 
management and profiles
                 Key: YARN-3926
             Project: Hadoop YARN
          Issue Type: New Feature
          Components: nodemanager, resourcemanager
            Reporter: Varun Vasudev
            Assignee: Varun Vasudev

Currently, there are efforts to add support for various resource-types such as 
disk(YARN-2139), network(YARN-2140), and  HDFS bandwidth(YARN-2681). These 
efforts all aim to add support for a new resource type and are fairly involved 
efforts. In addition, once support is added, it becomes harder for users to 
specify the resources they need. All existing jobs have to be modified, or have 
to use the minimum allocation.

This ticket is a proposal to extend the YARN resource model to a more flexible 
model which makes it easier to support additional resource-types. It also 
considers the related aspect of “resource profiles” which allow users to easily 
specify the various resources they need for any given container.
