OptimizeShuffleWithLocalRead

object OptimizeShuffleWithLocalRead extends Rule[SparkPlan] with AQEShuffleReadRule

A rule to optimize the shuffle read to local read iff no additional shuffles will be introduced: 1. if the input plan is a shuffle, add local read directly as we can never introduce extra shuffles in this case. 2. otherwise, add local read to the probe side of broadcast hash join and then run EnsureRequirements to check whether additional shuffle introduced. If introduced, we will revert all the local reads.
