如何正确格式化pyspark日志文件

import logging
from pyspark.sql import SparkSession

spark = SparkSession.builder.appName("LogFormatting").getOrCreate()

spark.sparkContext.setLogLevel("INFO")

sc = spark.sparkContext
log4jLogger = sc._jvm.org.apache.log4j
log4jLogger.LogManager.getLogger("org").setLevel(log4jLogger.Level.INFO)

log_format = "%(asctime)s %(levelname)s %(message)s"

log_file = "path/to/logfile.log"
logging.basicConfig(filename=log_file, format=log_format, level=logging.INFO)

logging.info("This is an info message")
logging.warning("This is a warning message")
logging.error("This is an error message")
