flink1.11好像是用的log4j2，我的mainjar用到了log4j, 两者类有冲突，导致JM、TM日志为空。
SLF4J: Class path contains multiple SLF4J bindings. SLF4J: Found binding in [jar:file:/opt/job.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: Found binding in [jar:file:/opt/flink-1.11.1-k8s/lib/log4j-slf4j-impl-2.12.1.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation. 目前 1、mainjar中的log4j不能完全去掉，毕竟有很多地方在用，而且后期新增依赖也有可能会用，不太可行 大家又啥好办法嘛 -- Sent from: http://apache-flink.147419.n8.nabble.com/
