I'm so silly I forgot to edit the hadoop-site.xml Why didn't hadoop project use a default hadoop-site.xml instand of the blank one~~~

Does that means I have to turn off the UAC? It seems useless just run cygwin using Run as administrator!! Thanks for your answering~~

I think it is because of Vista's User Access Control (UAC), so you should start command prompt as administrator.



I'm running hadoop example in vista with cygwin

Everything seems OK in setup, but when I run the example the error below happens.
