LuciferYang opened a new pull request #30255: URL: https://github.com/apache/spark/pull/30255
### What changes were proposed in this pull request? There are two similar compilation warnings about procedure-like declaration in Scala 2.13: ``` [WARNING] [Warn] /spark/core/src/main/scala/org/apache/spark/HeartbeatReceiver.scala:70: procedure syntax is deprecated for constructors: add `=`, as in method definition ``` and ``` [WARNING] [Warn] /spark/core/src/main/scala/org/apache/spark/storage/BlockManagerDecommissioner.scala:211: procedure syntax is deprecated: instead, add `: Unit =` to explicitly declare `run`'s return type ``` this pr is the first part to resolve SPARK-33352： - For constructors method definition add `=` to convert to function syntax - For without `return type` methods definition add `: Unit =` to convert to function syntax ### Why are the changes needed? Eliminate compilation warnings in Scala 2.13 and this change should be compatible with Scala 2.12 ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested?
