Subject Can not follow Single Node Setup example.
Date Wed, 26 Jun 2013 14:53:23 GMT
Hi,

http://hadoop.apache.org/docs/r1.1.2/single_node_setup.html

I followed the above instructions. But I get the following errors.
Does anybody know what is wrong? Thanks.

~/Downloads/hadoop-install/hadoop$ bin/hadoop jar
hadoop-examples-*.jar grep input output 'dfs[a-z.]+'
