[jira] [Created] (YARN-3482) Report NM available resources in heartbeat

Inigo Goiri created YARN-3482:
---------------------------------

             Summary: Report NM available resources in heartbeat
                 Key: YARN-3482
                 URL: https://issues.apache.org/jira/browse/YARN-3482
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: nodemanager, resourcemanager
    Affects Versions: 2.7.0
            Reporter: Inigo Goiri


NMs are usually collocated with other processes like HDFS, Impala or HBase. To manage this scenario correctly, YARN should be aware of the actual available resources. The proposal is to have an interface to dynamically change the available resources and report this to the RM in every heartbeat.
