不清楚什么原因?求大神解答
这个插件是我个人编译的
步骤如下:
一、资源:
插件源码hadoop2x-eclipse-plugin-master
hadoop-2.7.2
eclipse-luna-4.4
64位系统
二、修改插件内容:D:\hadoop2x-eclipse-plugin-master\src\contrib\eclipse-plugin\ivy\libraries.properties将文件中的jar包版本与hadoop-2.7.2对应,直接ant编译,通过!
三、eclipse安装插件
IP地址与port对应core-site.xml配置
最后DFSlocation连接的时候出错图片说明

Talent_em no,并不是防火墙原因,已经关闭了防火墙!当我在虚拟机centos中安装eclipse,并且编译插件,连接hadoop会出现同样的问题。还是报错
3 年多之前 回复

我替换hadoop-2.6.5编译之后,插件可用,没有错误。(ps:不清楚是之前2.7.2配置有错,还是本身版本问题。与hadoop-2.7.2配置唯一的改动是jdk配置为全局变量/etc/profile,之前是针对用户)

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

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。。。。。
