我想停止火花壳上的各种消息.
我试图编辑该log4j.properties文件以阻止这些消息.
这是内容 log4j.properties
# Define the root logger with appender file
log4j.rootCategory=WARN, console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.target=System.err
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%d{yy/MM/dd HH:mm:ss} %p %c{1}: %m%n
# Settings to quiet third party logs that are too verbose
log4j.logger.org.eclipse.jetty=WARN
log4j.logger.org.eclipse.jetty.util.component.AbstractLifeCycle=ERROR
log4j.logger.org.apache.spark.repl.SparkIMain$exprTyper=INFO
log4j.logger.org.apache.spark.repl.SparkILoop$SparkILoopInterpreter=INFO
但是消息仍在控制台上显示.
以下是一些示例消息
15/01/05 15:11:45 INFO SparkEnv: Registering BlockManagerMaster
15/01/05 15:11:45 INFO DiskBlockManager: Created local directory at /tmp/spark-local-20150105151145-b1ba

15/01/05 15:11:45 INFO ConnectionManager: Bound socket to port 44728 with id = ConnectionManagerId(192.168.100.85,44728)
15/01/05 …我正在尝试在spark执行器中使用自定义log4j appender,以便将所有日志转发到Apache Kafka.
问题是,在使用appender注册fatjar的类加载器之前初始化log4j,所以我最终得到以下结果:
log4j:ERROR Could not instantiate class [kafka.producer.KafkaLog4jAppender].
