> spark.blacklist.killBlacklistedExecutors is defined asĀ 
> (Experimental) If set to "true", allow Spark to automatically kill, and attempt to re-create,
executors when they are blacklisted. Note that, when an entire node is added to the blacklist,
all of the executors on that node will be killed.
> I presume the killing of blacklisted executors only happens after the stage completes
successfully and all tasks have completed or on fetch failures (updateBlacklistForFetchFailure/updateBlacklistForSuccessfulTaskSet).
It is confusing because the definition states that the executor will be attempted to be recreated
as soon as it is blacklisted. This is not true while the stage is in progress and an executor
is blacklisted, it will not attempt to cleanup until the stage finishes.
