Hi All,
I've set up the eclipse environment and built all of hadoop in it successfuly.
Then I tried to run the wordcount example in Eclipse but got the following
error messages:
---------------
Exception in thread "main" java.lang.RuntimeException: java.io.IOException: No

... 4 more

BTW, I can successfully run the wordcount example in my cgywin environment by
issuing below command:
bin/hadoop jar build/hadoop-0.16.0-examples.jar wordcount test-in test-out
How can I run it in Eclipse? Could you please help me. Thanks!
