Github user jinxing64 commented on the issue: https://github.com/apache/spark/pull/19602 @cloud-fan Sorry for late reply, so busy these days. In current change: 1. I follow `Cast.mayTruncate` strictly when extract partition Attribute; 2. I created new test data in `HiveClientSuite` and `testMetastorePartitionFiltering` can be used for validation for tables with different partitions schema. If needed, I can create more tests -- different binary comparisons and different datatypes.
