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.
