> Key: SPARK-2590

> {{SparkSQLOperationManager}} uses {{RDD.toLocalIterator}} to collect the
> result set one partition at a time. This is useful to avoid OOM when the
> result is large, but introduces extra job scheduling costs as each partition
> is collected with a separate job. Users may want to disable this when the
> result set is expected to be small.
