[python] Spark에서 정보 로깅을 해제하는 방법은 무엇입니까?

AWS EC2 안내서를 사용하여 Spark를 설치했으며 bin/pyspark스크립트를 사용하여 프로그램을 시작 하여 Spark 프롬프트를 표시하고 Quick Start 종료를 성공적으로 수행 할 수 있습니다.

그러나 필자의 삶에서는 INFO각 명령 후에 모든 자세한 로깅 을 중지하는 방법을 알 수 없습니다 .

응용 프로그램을 시작하는 폴더와 각 노드 에서 내 log4j.properties파일 의 아래 코드 (댓글 작성, OFF로 설정)에서 거의 모든 가능한 시나리오를 시도했지만 conf아무것도 수행하지 않습니다. INFO각 문을 실행 한 후에도 여전히 로깅 문이 인쇄됩니다.

이것이 어떻게 작동해야하는지 매우 혼란스러워합니다.

# - SPARK_PUBLIC_DNS, to set the public dns name of the driver program
# - SPARK_CLASSPATH=/root/spark-1.0.1-bin-hadoop2/conf/

# Options read by executors and drivers running inside the cluster
# - SPARK_LOCAL_IP, to set the IP address Spark binds to on this node
