Github user cloud-fan commented on the pull request: https://github.com/apache/spark/pull/10128#issuecomment-161626933 I think it's not a good example to show that we need to allow nondeterministic expressions in join codition. We can use `Repartition` operator to fix data skew, like `sqlContext.table(tblName).repartition(numPartitions).registerTempTable`, which looks better than your random join approach. Do you find other cases that need to use nondeterministic expressions in join codition?
