    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?
