             Summary: Metric for aggregated resources allocation per queue
                 Key: YARN-4236
                 URL: https://issues.apache.org/jira/browse/YARN-4236
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Chang Li
            Assignee: Chang Li


We currently track allocated memory and allocated vcores per queue but we don't 
have a good rate metric on how fast we're allocating these things. In other 
words, a straight line in allocatedmb could equally be one extreme of no new 
containers are being allocated or allocating a bunch of containers where we 
free exactly what we allocate each time. Adding a resources allocated per 
second per queue would give us a better insight into the rate of resource churn 
on a queue. Based on this aggregated resource allocation per queue we can 
easily have some tools to measure the rate of resource allocation per queue.
