> I'm running into an issue where the hadoop namenode fails to start hdfs when using openjdk 8. It appears to be because the namenode scripts rely on the bigtop-detect-javahome script in bigtop_utils, which doesn't detect JAVA_HOME correctly for openjdk 8.
> I'd like to modify the script so that it first tries to figure out java home by looking in /etc/alternatives and deriving JAVA_HOME from the symlink to the java executable. This should work on both Redhat and Debian based distros, in a forwards compatible way. The script would fall back to the more manual process for distros that don't use /etc/alternatives.
> Will submit a patch soon ....
