eclipse连接hadoop报错Could not obtain block

1.hadoop2.7.7版本

2报错截图图片说明

3.没有出现挂datanode的问题[图片]

图片说明

4.可以从web端正常访问和下载

1个回答

请求namenode返回datanode的内网ip,通过修改本地 hosts 文件,把 namenode、datanode 的外网 IP 和 hostname 的映射关系加进去(前提是得有外网IP)

然后在代码中设置:

Configuration conf = new Configuration();
conf.set("dfs.client.use.datanode.hostname", "true");

就可以了

急 eclipse 乱报错,求大佬帮忙

eclipse关闭时没有任何问题,但是打开时总是报一些很奇怪的错误,实际上这些代码是没有错误的,在任何位置换行或者是加一个空格保存一下就不报错了 比如![图片说明](https://img-ask.csdn.net/upload/201906/16/1560671282_369287.png) 然后吧括号去掉 ![图片说明](https://img-ask.csdn.net/upload/201906/16/1560671342_379865.png) 再保存一下就不报错了 再重启eclipse一下又·报错了又加上括号又保存一次就不报错了 错误是·The type String is not visible 这是怎么回事

hadoop编译报错,跪求解答

windows下eclipse连接虚拟机(linux)上的hadoop失败,求救啊!!

宿主电脑:windows 8.1 虚拟机:CentOS 6.4 防火墙一直是关着的 ,静态IP:192.168.233.136 eclipse:eclipse-jee-indigo-SR2-win32-x86_64 安在windows上, hadoop:1.2.1 主机和虚拟机间可以互相ping通,但是虚拟机无法上网(主机可以)。 在此之前搜索了好多网上连接hadoop的方法,hadoop-eclipse的插件安好了,配置如图:(虚拟机用户名:wuxiteng)![图片说明](https://img-ask.csdn.net/upload/201610/18/1476802850_276181.png) 详细配置是按网上搜的配的,不知是不是导致失败的原因。总之,设置好后,(hadoop已启动),在左侧的DFSLocations处一直提示正在连接,最后显示连接失败。网上有好多说法,有的说和主机用户名有关,有的说和环境变量有关,有的说和防火墙有关,弄了好几天了,实在不懂是哪错了,大神们,求救啊。。。。。
