             Summary: Publish executor memory utilisation in heartbeat events
                 Key: SPARK-23910
                 URL: https://issues.apache.org/jira/browse/SPARK-23910
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 2.3.0
            Reporter: Gopala


Is it possible to send the executor memory utilisation in the heart beat 
events? 
While this detail is pretty easily available in Map Reduce, there doesn't seem 
to be a way to get this inclusive of all types of memory segments used by Spark 
( memory used for storage can be determined, but not that used for execution ) 
. 
We find this feature very critical to determine the memory utilisation and plan 
the resources appropriately.
