[jira] [Created] (SPARK-12895) Implement TaskMetrics using accumulators

Andrew Or created SPARK-12895:
---------------------------------

             Summary: Implement TaskMetrics using accumulators
                 Key: SPARK-12895
                 URL: https://issues.apache.org/jira/browse/SPARK-12895
             Project: Spark
          Issue Type: Sub-task
          Components: Spark Core
            Reporter: Andrew Or
            Assignee: Andrew Or


We need to first do this before we can avoid sending TaskMetrics from the executors to the driver. After we do this, we can send only accumulator updates instead of both that AND TaskMetrics.

But first, we need to express everything in TaskMetrics as accumulators.
