Subject [jira] [Created] (YARN-1858) Allow containers can be allocated in groups
Date Thu, 20 Mar 2014 02:15:43 GMT
Michael Lv created YARN-1858:
--------------------------------

             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.
