Wenchen Fan bf764a33be [SPARK-22384][SQL][FOLLOWUP] Refine partition pruning when attribute is wrapped in Cast ... ## What changes were proposed in this pull request? As mentioned in https://github.com/apache/spark/pull/21586 , `Cast.mayTruncate` is not 100% safe, string to boolean is allowed. Since changing `Cast.mayTruncate` also changes the behavior of Dataset, here I propose to add a new `Cast.canSafeCast` for partition pruning. ## How was this patch tested? new test cases Author: Wenchen Fan <wenchen@databricks.com> Closes #21712 from cloud-fan/safeCast.		2018-07-04 18:36:09 -07:00
