[jira] [Created] (SPARK-5701) Only set ShuffleReadMetrics when task does a shuffle

Kay Ousterhout created SPARK-5701:
-------------------------------------

             Summary: Only set ShuffleReadMetrics when task does a shuffle
                 Key: SPARK-5701
                 URL: https://issues.apache.org/jira/browse/SPARK-5701
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 1.3.0, 1.2.1
            Reporter: Kay Ousterhout
            Priority: Minor


The updateShuffleReadMetrics method in TaskMetrics (called by the executor heartbeater) will currently always add a ShuffleReadMetrics to TaskMetrics (with values set to 0), even when the task didn't read any shuffle data.  ShuffleReadMetrics should only be added if the task reads shuffle data.
