MaxGekk opened a new pull request #30474: URL: https://github.com/apache/spark/pull/30474
### What changes were proposed in this pull request? In the PR, I propose to changes the resolver of partition specs used in V2 `ALTER TABLE .. ADD/DROP PARTITION` (at the moment), and re-use `CAST` in conversion partition values to desired types according to the partition schema. ### Why are the changes needed? Currently, the resolver of V2 partition specs supports just a few types: https://github.com/apache/spark/blob/23e9920b3910e4f05269853429c7f18888cdc7b5/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/ResolvePartitionSpec.scala#L72, and fails on other types like date/timestamp. ### Does this PR introduce _any_ user-facing change? Yes ### How was this patch tested?
