Subject [jira] [Created] (YARN-423) Create a simple prioritized task assignment module
Date Mon, 25 Feb 2013 07:02:12 GMT
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.
