> The Hadoop packages go through some effort (see /usr/lib/hadoop-0.20/bin/hadoop-config.sh)
to guess at a good JVM to use if JAVA_HOME isn't set. For example, if both OpenJDK and Oracle
JDK are installed, hadoop-config.sh will choose Oracle every time. Other packages that Bigtop
integrates, don't follow the same practice (ZK, Pig, etc.). It would be nice to have this
common code shared.
