SPRKPY1047

pyspark.context.SparkContext.setLogLevel has workaround

Description

This issue appears when the tool detects the usage of pyspark.context.SparkContext.setLogLevel which has a workaround.

Input code:

sparkSession.sparkContext.setLogLevel("WARN")

Output code:

#EWI: SPRKPY1047 => pyspark.context.SparkContext.setLogLevel has a workaround, see documentation for more info
sparkSession.sparkContext.setLogLevel("WARN")

Scenario

setLogLevel(self, logLevel: str) -> None

Action: Replace the "setLogLevel" function usage with "logging.basicConfig" that provides a set of convenience functions for simple logging usage. In order to use it, we need to import two modules, "logging" and "sys", and the level constant should be replaced using the "Level equivalent table":

Example:

import logging
import sys
logging.basicConfig(stream=sys.stdout, level=logging.WARNING)

Level equivalent table

Level source parameter	Level target parameter
"ALL"	This has no equivalent
"DEBUG"	logging.DEBUG
"ERROR"	logging.ERROR
"FATAL"	logging.CRITICAL
"INFO"	logging.INFO
"OFF"	logging.NOTSET
"TRACE"	This has no equivalent
"WARN"	logging.WARNING
