Probably not the best way, but one possible way: make a call to
Runtime.exec() and call "hadoop -version".

Sorry, make that "hadoop version".
Also, FYI, it looks like that command just calls out to methods in
http://hadoop.apache.org/docs/r0.20.2/api/org/apache/hadoop/util/VersionInfo.html
. So you can probably query those directly.
