hadoop程序在windows上访问hdfs的问题
hadoop运行在linux上，在window的本地eclips运行java代码，碰到如下的异常，java.lang.IllegalArgumentException: Wrong FS: hdfs:/ expected file:///
Java代码如下：
FileSystem fs = FileSystem.get(conf);
in = fs.open(new Path("hdfs://192.168.2.6:9000/user/hadoop/output/part-00000"));
抛出异常如下：
Exception in thread "main" java.lang.IllegalArgumentException: Wrong FS: hdfs://192.168.2.6:9000/user/hadoop/output/part-00000, expected: file:///

解决方案：
hadoop需要把集群上的core-site.xml和hdfs-site.xml放到当前工程下。eclipse工作目录的bin文件夹下面
因为是访问远程的HDFS 需要通过URＩ来获得FileSystem. 版权声明：本文为博主原创文章，未经博主允许不得转载。
