SPRKPY1047

pyspark.context.SparkContext.setLogLevel

This issue code has been deprecated since Spark Conversion Core Version 4.6.0

Description

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

Scenario

Input

Below is an example of the usage of the method setLogLevel.

sparkSession.sparkContext.setLogLevel("WARN")

Output

The tool adds the EWI SPRKPY1047 indicating that a workaround can be implemented.

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

Recommended fix

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":

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
