java连接hadoop报错： Caused by: java.lang.IllegalArgumentException: LoggerFactory is not a Logback Logger

Caused by: java.lang.IllegalArgumentException: LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. Either remove Logback or the competing implementation (class org.slf4j.impl.Log4jLoggerFactory loaded from file:/usr/local/tomcat/webapps/hadoop/WEB-INF/lib/slf4j-log4j12-1.7.26.jar). If you are using WebLogic you will need to add 'org.slf4j' to prefer-application-packages in WEB-INF/weblogic.xml: org.slf4j.impl.Log4jLoggerFactory
是maven加载hadoop的依赖包之后，启动项目出现了以上异常
这个异常是jar包的冲突，删除掉slf4j-log4j12-1.7.26.jar就可以了
我们在maven依赖中对hadoop-hdfs和hadoop-client的依赖都去除slf4j-log4j12依赖即可

我的项目是部署在linux中的docker上的，然后重新打包运行，启动成功了
