TaskMetrics

:: DeveloperApi :: Metrics tracked during the execution of a task.

This class is used to house metrics both for in-progress and completed tasks. In executors, both the task thread and the heartbeat thread write to the TaskMetrics. The heartbeat thread reads it to send in-progress metrics, and the task thread reads it to send metrics along with the completed task.

So, when adding new fields, take into consideration that the whole object can be serialized for shipping off at any time to consumers of the SparkListener interface.
