> This is reproducible by looking in the SQL UI for the Sort operator spill metrics after running the following query:
> {code}
> scala> val table = spark.range(0, 1000000000)
> table: org.apache.spark.sql.Dataset[Long] = [id: bigint]
> scala> table.join(table, "id").count()
> res0: Long = 1000000000                                                         
> {code}
> If off-heap memory is enabled, e.g. bin/spark-shell --master=local-cluster[1,16,250000] --conf spark.executor.memory=2g --driver-memory 1g --conf spark.memory.offHeap.enabled=true --conf spark.memory.offHeap.size=15g, then the spill metric will always be zero.
