>             Project: Spark
>          Issue Type: Bug
>          Components: Scheduler
>    Affects Versions: 1.2.0, 1.3.0, 1.4.0, 1.5.0

> RDD.getPreferredLocations() and RDD.getPartitions() may throw exceptions but the DAGScheduler does not guard against this, leaving it vulnerable to crashing and stopping the SparkContext if exceptions occur there.
> We should fix this by adding more try blocks around these calls in DAGScheduler.
