Description

Apache Hadoop YARN's ResourceRequest mechanism is the core part of the YARN's scheduling API for applications to use. The ResourceRequest mechanism is a powerful API for applications (specifically ApplicationMasters) to indicate to YARN what size of containers are needed, and where in the cluster etc.

However a host of new feature requirements are making the API increasingly more and more complex and difficult to understand by users and making it very complicated to implement within the code-base.

This JIRA aims to generalize and unify all such scheduling-strategies in YARN.
