-----------------------------------
Oops actually this was already done in SPARK-14069. Closing this as duplicate.
> Expose more executor stats in stable status API
> -----------------------------------------------

> Key: SPARK-13269
> URL: https://issues.apache.org/jira/browse/SPARK-13269
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Reporter: Andrew Or
> Fix For: 2.0.0
>
>
> Currently the stable status API is quite limited; it exposes only a small
> subset of the things exposed by JobProgressListener. It is useful for very
> high level querying but falls short when the developer wants to build an
> application on top of Spark with more integration.
> In this issue I propose that we expose at least two things:
> - Which executors are running tasks, and
> - Which executors cached how much in memory and on disk
> The goal is not to expose exactly these two things, but to expose something
> that would allow the developer to learn about them. These concepts are very
> much fundamental in Spark's design so there's almost no chance that they will
> go away in the future.
