[SPARK-7955][Core] Ensure executors with cached RDD blocks are not reâ¦
â¦moved if dynamic allocation is enabled.
This is a work in progress. This patch ensures that an executor that has
cached RDD blocks are not removed,
but makes no attempt to find another executor to remove. This is meant to
get some feedback on the current
approach, and if it makes sense then I will look at choosing another
executor to remove. No testing has been done either.
