这是SecureCRT下面的代码异常，相关SSH和Hadoop配置文件已经完成，而且Hadoop运行成功，但是在主节点查看Hadoop状态时出现此异常。网上的解决方式大多是删除节点下面的数据，然后reboot，尝试了一下，没有成功，现在此该如何解决，求高手解答！

没有人回帖！

解决，可能是在查看状态前未启动所有的节点！

把ip地址改为主节点的主机名称就没了，话说楼主有遇到dfs容量一直为0kb的吗，datanode就是一直连接不了namenode，但是从datanode ssh登录到namenode没有吗？

namenode format 了木有内吗？

INFO ipc.Client: Retrying connect to server: localhost/127.0.0.1:9000. Already tried 0 time(s).原因：由于 dfs 的部分文件默认保存在tmp文件夹，在系统重启时被删除。解决：修改core-site.xml 的 hadoop.tmp.dir配置文件路径：/home/hadoop/tmp。
其实很多种错误，我尝试过很多，我有时遇到解决了，有一次遇到了，到处论坛，网页，满大街都没找到方法，最后是重装的hadoop包，在重新发给datanode......够悲催的，可以baidu，google下，很多。真心希望你能解决.....
