There is a current bug where the dga-config.xml located in distributed-graph-analytics/dga-giraph/main/resources is included in the
uber jar that distDGA builds; this is a legacy issue from our attempt at adding this resource to YARN - which we don't even fully
support yet. To make configuration changes for your cluster, please make them in this file and rebuild the uber jar. You can still
override every setting in the configuration file via the command line.
