Description

Example codes from: http://hadoop.apache.org/common/docs/r0.21.0/single_node_setup.html

Section "Standalone Operation"
the line "bin/hadoop jar hadoop-*-examples.jar grep input output 'dfs[a-z.]+' " can not run correctly, because the example jar in the directory is "hadoop-mapred-examples-0.21.0.jar", include a revision number.
the command should be " bin/hadoop jar hadoop*examples*.jar grep input output 'dfs[a-z.]+' "

And in section "Pseudo-Distributed Operation / Execution", also refered a command using hadoop*exapmples.jar, it also should be changed.
