--------------------------------------
Summary: Improve resource scheduling
Key: MAPREDUCE-4256
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4256
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: resourcemanager
Reporter: Radim Kolar
Fix For: 2.0.0, 3.0.0
Currently resource manager supports only Memory resource during container
allocation.
I propose following improvements:
1. add support for CPU utilization. Node CPU used information can be obtained
by ResourceCalculatorPlugin.
2. add support for custom resources. In node configuration will be something
like:
name=node.resource.GPU, value=1 (node has 1 GPU).
If job will need to use GPU for computation, it will add "GPU=1" requirement to
its job config and Resource Manager will allocate container on node with GPU
available.
