Avery Ching commented on GIRAPH-391:
------------------------------------

Thanks for taking a look at this Ravi.  Unfortunately, your patch breaks unittests (try running
'mvn clean install').  Can you please rework it?

> Distributed Cache behaviour has changed in Hadoop 0.23. 
> When running on the PageRankBenchmark on a pseudo-distributed setup, GraphMapper.java:303
returns null
> bq. Path[] fileClassPaths = DistributedCache.getLocalCacheArchives(conf);
> Further, context.getJar() returns the location of the job jar in *HDFS* . Obviously this
can't be added to the classpath. If we only checked for the existence of this jar file, it
would follow on to using the findContainingJar() method which returns the right thing.
