Sean Owen commented on SPARK-16158:
-----------------------------------
I would generally not favor these types of changes. They end up revealing that
there are a number of unspoken assumptions about how dynamic allocation works
that are not easily refactorable into something pluggable. If there's not a
compelling use case for something different I don't think we'd want the
complexity.

> It would be nice if Spark supports plugging in custom dynamic allocation
> heuristics. This feature would be useful for experimenting with new
> heuristics and also useful for plugging in different heuristics per job etc.
