log4j2.properties调优以仅为Spark设置特定的日志级别

Question

我正在将我的工作项目的log4j更新为log4j2，并试图掌握在这两个API之间发生变化的一些语法。

我从他们的网站上提取了一个示例log4j2.properties，如下所示。由于Spark在信息级别上是超级嘈杂的，我所需要做的就是设置控制台附加器来过滤来自'org.apache.spark‘的WARN下面的日志。在旧的应用程序接口中，这只是log4j.logger.org.apache.spark=WARN，但现在看起来并不那么简单。

任何建议都将不胜感激。

尝试在您的配置文件中添加以下行-

logger.org.apache.spark.name = org.apache.spark
logger.org.apache.spark.level = warn
logger.org.apache.spark.additivity = false
logger.org.apache.spark.appenderRef.rolling.ref = RollingFile
logger.org.apache.spark.appenderRef.stdout.ref = STDOUT
