主题: Problem running sample Grep

Hello,

 

I am new to Hadoop.  After setting my testing environment (which I am not
sure if it is correct), I tried to run the Grep sample by

Bin/hadoop org.apache.hadoop.samples.Grep myinput myoutput 'dfs'

However, it always says 'Exception in thread "main"
java.lang.NoClassDefFoundError: org/apache/hadoop/examples/Grep'

I didn't know what went wrong.

Any help is appreciated.  Thanks.

 

Best Regards

 

Richard Yang
