> These two lines in {{SparkGraphComputer}} assume that {{HADOOP_GREMLIN_LIBS}} will only contain local file system references (although it seems that the rest of the code could handle DFS references):
> {code}
> final String[] paths = hadoopGremlinLocalLibs.split(":");
> final FileSystem fs = FileSystem.get(hadoopConfiguration);
> {code}
> If, for example, {{HADOOP_GREMLIN_LIBS}} would be set to {{hdfs:///spark-gremlin-libs:/foo/bar}}, the {{split(":")}} call would obviously separate the file system scheme ({{hdfs://}}) from the path ({{/spark-gremlin-libs}}).
> Next, {{FileSystem.get(hadoopConfiguration)}} will always only return a reference to the {{FileSystem}} that is defined as the default file system.
> The same is probably true for {{GiraphGraphComputer}}.
