             Summary: Show fetch wait time as optional metric in the UI
                 Key: SPARK-5326
                 URL: https://issues.apache.org/jira/browse/SPARK-5326
             Project: Spark
          Issue Type: Improvement
    Affects Versions: 1.2.0
            Reporter: Kay Ousterhout
            Assignee: Kay Ousterhout
            Priority: Minor


Time blocked waiting on shuffle read time can be a cause of slow jobs.  We 
currently store this information but don't show it in the UI; we should add it 
to the UI as an optional additional metric.
