We need to set num partitions just to cheat Exchange of Spark.
We need to set num partitions just to cheat Exchange of Spark. This partition is not used for actual scan operator which depends on the actual RDD. Spark ClusteredDistribution is pretty simplistic to consider numShufflePartitions for its partitioning scheme as Spark always uses shuffle. Ideally it should consider child Spark plans partitioner.
