为什么运行在pycharm中的pyspark代码会生成这些信息？

Question

我是蟒蛇和火种的绿色手。当我在py魅力中运行pyspark的代码时，它总是生成下面的信息。我想知道原因和解决办法。

Using Spark's default log4j profile: org/apache/spark/log4j-defaults.properties
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).
    
�ɹ�: ����ֹ PID 15608 (���� PID 9980 �ӽ���)�Ľ��̡�
�ɹ�: ����ֹ PID 9980 (���� PID 7560 �ӽ���)�Ľ��̡�
�ɹ�: ����ֹ PID 7560 (���� PID 13296 �ӽ���)�Ľ��̡�

我最近也面临着同样的问题。我通过添加以下代码来修正它：

import os
os.system('chcp 65001') # explicitly changed encoding to utf-8

Using Spark's default log4j profile: org/apache/spark/log4j-defaults.properties
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).

SUCCESS: The process with PID 14228 (child process of PID 21804) has been terminated.
SUCCESS: The process with PID 21804 (child process of PID 9792) has been terminated.
SUCCESS: The process with PID 9792 (child process of PID 26488) has been terminated.
