Dear all,
I tried to run the PI example program like this:
	$ bin/hadoop jar hadoop-0.10.1-examples.jar pi 100 100
But the result turned out to be 0.0. Is it correct? Or there must be
something wrong with the setup of Hadoop on my server.

BTW, is there a program to see the states of running nodes? I think I need
one to check if programs run smoothly on datanodes.

Best wishes,
Liqi Gao
