>    Affects Versions: 2.1.0

> If you run
> {code}
> sc.parallelize(1 to 100000, 100000).map(identity).count()
> {code}
> then {{TaskSetManager.abortIfCompletelyBlacklisted()}} is the number-one performance hotspot in the scheduler, accounting for over half of the time. This method was introduced in SPARK-15865, so this is a performance regression in 2.1.0-SNAPSHOT.
