Bad connection to FS. command aborted. exception: Call to chaoren/192.168.80.100:9000 failed on connection exception: java.net.ConnectException: Connection refused

错误解决方法：

1、先将/usr/local/hadoop/tmp/dfs文件夹整个删除掉（cd /usr/local/hadoop/tmp rm -rf dfs）

2、再将namenode进行格式化（hadoop namenode -format）

3、格式化成功后，最后重启hadoop（cd /usr/local/hadoop/bin start-all.sh）

4、重启完Hadoop之后，再重新连接hdfs即可（hadoop fs -ls hdfs://chaoren:9000/）。
