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
