LuciferYang opened a new pull request #30234: URL: https://github.com/apache/spark/pull/30234
### What changes were proposed in this pull request? The purpose of this pr is to partial resolve SPARK-33285. `Auto-application` is dropped in Scala 3 and deprecated in 2.13 (https://github.com/scala/scala/pull/8833) now. So we should add the parens when accessed empty-paren method. For example, if definition as follows: ``` Class Foo { def bar(): Unit = {} } val foo = new Foo ``` `foo.bar()` is recommend , not `foo.bar`. So the main change of this pr is only add the parens where needed. ### Why are the changes needed? eliminate compilation warnings in Scala 2.13 ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? Pass the Jenkins or GitHub Action ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
