[169517388]

to hadoop.org：

    Hello hadoop.org. I'm the new guy who is learning the hadoop right now. I'v 
bulit a 5 nodes hadoop experimental environment. When I ran the MR program, the 
error came out.
    I searched a lot. Maybe the java runtime environment or anything else. I 
didn't get it.

hadoop with some friends. 
    So please, I'v already crazy, beause I'v been disturb by this problem for 
one week.
