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

             Summary: Executor UI improvement suggestions
                 Key: SPARK-1832
                 URL: https://issues.apache.org/jira/browse/SPARK-1832
             Project: Spark
          Issue Type: Improvement
          Components: Web UI
    Affects Versions: 1.0.0
            Reporter: Thomas Graves
             Fix For: 1.1.0


I received some suggestions from a user for the /executors UI page to make it more helpful. This gets more important when you have a really large number of executors.

     Fill some of the cells with color in order to make it easier to absorb the info, e.g.

RED if Failed Tasks greater than 0 (maybe the more failed, the more intense the red)
GREEN if Active Tasks greater than 0 (maybe more intense the larger the number)

Possibly color code COMPLETE TASKS using various shades of blue (e.g., based on the log(# completed)
- if dark blue then write the value in white (same for the RED and GREEN above

Maybe mark the MASTER task somehow
 
    Report the TOTALS in each column (do this at the TOP so no need to scroll to the bottom, or print both at top and bottom).
