Kay Ousterhout a46497eecc [SPARK-3984] [SPARK-3983] Fix incorrect scheduler delay and display task deserialization time in UI ... This commit fixes the scheduler delay in the UI (which previously included things that are not scheduler delay, like time to deserialize the task and serialize the result), and also adds information about time to deserialize tasks to the optional additional metrics. Time to deserialize the task can be large relative to task time for short jobs, and understanding when it is high can help developers realize that they should try to reduce closure size (e.g, by including less data in the task description). cc shivaram etrain Author: Kay Ousterhout <kayousterhout@gmail.com> Closes #2832 from kayousterhout/SPARK-3983 and squashes the following commits: 0c1398e [Kay Ousterhout] Fixed ordering 531575d [Kay Ousterhout] Removed executor launch time 1f13afe [Kay Ousterhout] Minor spacing fixes 335be4b [Kay Ousterhout] Made metrics hideable 5bc3cba [Kay Ousterhout] [SPARK-3984] [SPARK-3983] Improve UI task metrics.		2014-11-05 15:30:31 -08:00
