Help message is wrong for touchz command.
-----------------------------------------
Key: HADOOP-7193
URL: https://issues.apache.org/jira/browse/HADOOP-7193
Project: Hadoop Common
Issue Type: Improvement
Components: fs
Reporter: Uma Maheswara Rao G
Priority: Minor
Help message for touchz command is
-touchz <path>: Write a timestamp in yyyy-MM-dd HH:mm:ss format
in a file at <path>. An error is returned if the file exists
with non-zero length.
Actually current DFS behaviour is that it will not write any time stamp in
created file. Just it is creating zero size file.
So better to change the help message to give exact meaning.
