任何人都会帮忙。我是hadoop的新手。我按照这里的所有步骤:http://ebiquity.umbc.edu/Tutorials/Hadoop/00%20-%20Intro.html, 一切顺利,直到设置hadoop插件。在我尝试使用命令启动namenode之后:bin / hadoop namenode。它显示错误如下。

raj@raj-PC ~/hadoop-0.19.1
$ bin/hadoop namenode
cygwin warning:
  MS-DOS style path detected: C:\cygwin\home\raj\HADOOP~1.1\/build/native
  Preferred POSIX equivalent is: /home/raj/HADOOP~1.1/build/native
  CYGWIN environment variable option "nodosfilewarning" turns off this warning.
  Consult the user's guide for more details about POSIX paths:
