    Description

      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.
