日志配置文件选择使用log4j.properties flink程序不打印日志。

问题原因         日志依赖包冲突

解决办法         将lib目录下的log4j2依赖移除，如下：         log4j-1.2-api-2.12.1.jar         log4j-api-2.12.1.jar         log4j-core-2.12.1.jar         log4j-slf4j-impl-2.12.1.jar

log4j.properties

# This affects logging for both user code and Flink log4j.rootLogger=INFO, infoFile

# The following lines keep the log level of common libraries/connectors on # log level INFO. The root logger does not override this. You have to manually # change the log levels here. log4j.logger.akka=INFO log4j.logger.org.apache.kafka=INFO log4j.logger.org.apache.hadoop=INFO log4j.logger.org.apache.zookeeper=INFO

# Log all infos in the given file log4j.appender.infoFile=org.apache.log4j.RollingFileAppender log4j.appender.infoFile.File=${log.file} log4j.appender.infoFile.layout=org.apache.log4j.PatternLayout log4j.appender.infoFile.layout.ConversionPattern=%d{yyyy/MM/dd HH:mm:ss,SSS} %p %C.%M(%L) | %m%n log4j.appender.infoFile.append=true log4j.appender.infoFile.MaxFileSize=32MB log4j.appender.infoFile.MaxBackupIndex=128

# Suppress the irrelevant (wrong) warnings from the Netty channel handler log4j.logger.org.apache.flink.shaded.akka.org.jboss.netty.channel.DefaultChannelPipeline=ERROR, file

# We only log the kafka appender logs to File to avoid deadlocks log4j.logger.cloudera.shaded.org.apache.kafka=INFO, file log4j.additivity.cloudera.shaded.org.apache.kafka=false
