我想停止各种消息都是在火花壳。
我尝试编辑log4j。属性文件，以停止这些消息。
下面是log4j.properties的内容
# 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
但是消息仍然显示在控制台上。
下面是一些示例消息
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 HttpServer: Starting HTTP Server

我怎么阻止这些?
一个有趣的想法是使用此处建议的RollingAppender: http://shzhangji.com/blog/2015/05/31/spark-streaming-logging-configuration/
这样您就不会“污染”控制台空间，但仍然能够在$YOUR_LOG_PATH_HERE/${dm.logging.name}.log下看到结果。
log4j.rootLogger=INFO, rolling
log4j.appender.rolling=org.apache.log4j.RollingFileAppender
log4j.appender.rolling.layout=org.apache.log4j.PatternLayout
log4j.appender.rolling.layout.conversionPattern=[%d] %p %m (%c)%n
log4j.appender.rolling.maxFileSize=50MB
log4j.appender.rolling.maxBackupIndex=5
log4j.appender.rolling.file=$YOUR_LOG_PATH_HERE/${dm.logging.name}.log
log4j.appender.rolling.encoding=UTF-8
另一个解决原因的方法是观察你通常有什么样的日志记录(来自不同的模块和依赖)，并为每个日志设置粒度，同时将过于冗长的第三方日志“安静”:
例如,
# Silence akka remoting
log4j.logger.Remoting=ERROR
log4j.logger.akka.event.slf4j=ERROR
log4j.logger.org.spark-project.jetty.server=ERROR
log4j.logger.org.apache.spark=ERROR
log4j.logger.com.anjuke.dm=${dm.logging.level}
log4j.logger.org.eclipse.jetty=WARN
log4j.logger.org.eclipse.jetty.util.component.AbstractLifeCycle=ERROR
log4j.logger.org.apache.spark.repl.SparkIMain$exprTyper=INFO
log4j.logger.org.apache.spark.repl.SparkILoop$SparkILoopInterpreter=INFO
编辑conf/log4j。属性文件，并更改以下行:
log4j.rootCategory=INFO, console
to
log4j.rootCategory=ERROR, console
另一种方法是:
启动spark-shell并输入以下内容:
import org.apache.log4j.Logger
import org.apache.log4j.Level
Logger.getLogger("org").setLevel(Level.OFF)
Logger.getLogger("akka").setLevel(Level.OFF)
之后你就看不到任何日志了。
Level的其他选项包括:all、debug、error、fatal、info、off、trace、trace_int、warn
详细信息可以在文档中找到。
