[jira] [Created] (YARN-423) Create a simple prioritized task assignment module

Bikas Saha created YARN-423:
-------------------------------

             Summary: Create a simple prioritized task assignment module
                 Key: YARN-423
                 URL: https://issues.apache.org/jira/browse/YARN-423
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Bikas Saha
            Assignee: Bikas Saha


Most AM's need basic container to task assignment based on priority and location. Writing such a module would solve a large majority of use cases and help further hide the complexity of resource request translation in the RM allocate protocol. The module will handle assignment of containers to tasks based on simple priority order. The module will also handle cancellation of other preferred locations for a task that has been assigned a container.
