MapReduce程序都无法执行

之前eclipse连接到hdfs上开发是可以运行的，
现在，在输入hdfs://就出错了。

core,hdfs两个文件放在src路径下了

现在出现如下错误，说是没有DataNode节点, 只不过我是在Windows平台运行，放入集群是没有问题的

比较奇怪
1.首先楼主是几个datanode.如果是两个，那么其中一个被排除了。也就是一个datanode不能使用了。
2.在window下面开发，需要是jar包，本地的配置文件根本不需要读取的。
3.楼主的hdfs：//应该是连接的远程的吧，确保没有问题。

测试机器, 就一台机器, DataNode启动着，Jar包都是全的，防火墙没强相应的端口ip地址啥的都是对的。就是运行M/R在Windows Eclipse报错，集群运行无问题
因为要做调试，之前可以。换了个Eclipse版本貌似不行了

原先版本是否可以。
但是报的错误，似乎跟版本没有关系。
楼主换版本之后，是不是做什么操作了
或则集群已经产生问题，但是没有发现

楼主确定放到集群没有问题，那么只有一个可能性了，就是eclipse远程连接问题

之前的版本忘记多少来着了，集群可以保证没有问题的。
