> AbstractGangliaSink is used by the hadoop-metrics2 package to emit metrics to Ganglia. Currently, this class uses the apache commons-configuration package to read from the hadoop-metrics2.properties file. commons-configuration is outdated, and has a bug where the .getString function drops everything after the first comma. This change uses .getList instead, which will work for one or many Ganglia sink servers.
>
> This is fixed in trunk by upgrading to commons-configuration2, which doesn't have the bug anymore.
