以下步骤验证github上面的Flink最新版本(我也不知道最新版本号是啥，下面以1.11代称)到底修复这个warning没。
先操作1.10.1版本：
①$FLINK_HOME保留flink-conf.yaml,其余配置文件全部删除。
②删除$FLINK_HOME/bin下面的start-scala-shell.sh
借用最新版本的文件:
③git clone [http://github.com/flink]（这里是1.11版本）
④cd flink-dist/src/main/flink-bin/conf（这里是1.11版本）
⑤cp * $FLINK_HOME/conf（1.11版本的配置文件拷贝给1.10.1版本）
⑥cp flink-scala-shell/start-script/start-scala-shell.sh
$FLINK_HOME/bin（1.11版本的启动脚本拷贝给1.10.1版本）
测试:
⑦$FLINK_HOME/bin/start-scala-shell.sh local(警告依旧)
log4j:WARN No appenders could be found for logger
(org.apache.flink.configuration.GlobalConfiguration).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See [http://logging.apache.org/log4j/1.2/faq.html#noconfig] for
more info.
解决方案:
在log4j.properties文件末尾加入以下几行
log4j.rootLogger=INFO, console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%d\{dd/MM/yyyy HH:mm:ss.SSS}
