Owen O'Malley commented on HADOOP-567:
--------------------------------------

I'll change the script name and the field names.

The point of util.VersionStamp is isolating the upstream code from the 
possiblity that the BuildStamp class wasn't generated. In particular, it makes 
that system compilable even if the script fails for some reason (or isn't 
called). A typical case that would be if someone is using eclipse or some other 
IDE without using the ant build script.

I hadn't really looked at the Java Package stuff, but it seems like serious 
overkill for this context.

> It would be good to compile the Hadoop version, subversion revision, and 
> compilation date into the hadoop.jar file. 
> The web/ui would display the version for each of the server home page.
> I'd also add "bin/hadoop version" to print the version information.
