spark  java程序写完后，执行 java -jar jar包name报如下错误：

Exception in thread "main" com.typesafe.config.ConfigException$Missing: No configuration setting found for key 'akka.remote.log-sent-messages'

或者报

Exception in thread "main" java.lang.SecurityException: Invalid signature file digest for Manifest main attributes

那是打包时的配置问题，请用shade插件打包，修改pom.xml打包再运行
