--------------------------------
Summary: Allow containers can be allocated in groups
Key: YARN-1858
URL: https://issues.apache.org/jira/browse/YARN-1858
Project: Hadoop YARN
Issue Type: Improvement
Components: resourcemanager
Affects Versions: 2.3.0
Reporter: Michael Lv
Currently when applications running on YARN send resource request to RM to
allocate resources, after the response is received, there is no good way to
associate the results with the original request. We propose to add a field in
each request to identify the resource request, so the resource received can be
grouped to resource requests. This new field can be user managed and YARN only
need to carry this field forward into the responses so user application can
associate the received resources with the original request.
