----------------------------------

             Summary: Sort time metric
                 Key: SPARK-15259
                 URL: https://issues.apache.org/jira/browse/SPARK-15259
             Project: Spark
          Issue Type: Bug
          Components: SQL
            Reporter: Eric Liang
            Priority: Minor


After SPARK-14669 it seems the sort time metric includes both spill and record 
insertion time. This makes it not very useful since the metric becomes close to 
the total execution time of the node.

We should track just the time spent for in-memory sort, as before.
