Logging

trait Logging extends AnyRef

:: DeveloperApi :: Utility trait for classes that want to log data. Creates a SLF4J logger for the class and allows logging messages at different levels using methods that only evaluate parameters lazily if the log level is enabled.

NOTE: DO NOT USE this class outside of Spark. It is intended as an internal utility. This will likely be changed or removed in future releases.
