advancedxy opened a new pull request, #42255: URL: https://github.com/apache/spark/pull/42255
### What changes were proposed in this pull request? Parse string parameter in hint method into expressions so that it would be easier for other languages to specify hint requirements. ### Why are the changes needed? This is a rework of #37616. Before this commit, there's no way for users to directly specify hint info that include column info in PySpark's hint method. ### Does this PR introduce _any_ user-facing change? Yes. PySpark and Spark for R uses may specify rebalance and repartition hint with ease. ### How was this patch tested? Added UTs. -- This is an automated message from the Apache Git Service.
