> Key: SPARK-8606
> URL: https://issues.apache.org/jira/browse/SPARK-8606
> Project: Spark
> Issue Type: Bug
> Components: Scheduler
> Affects Versions: 1.2.0, 1.3.0, 1.4.0, 1.5.0
> Reporter: Josh Rosen
> Assignee: Josh Rosen
> Priority: Critical
>
> 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.
