Khalid El-Arini commented on GIRAPH-510:
----------------------------------------

The problem is that in the Facebook release of Hadoop, the DataNode class only 
defines the runDatanodeDaemon method with no arguments (cf. 
https://github.com/facebook/hadoop-20/blob/master/src/hdfs/org/apache/hadoop/hdfs/server/datanode/DataNode.java),
 whereas in the standard Apache release, the runDatanodeDaemon method takes a 
single argument.  It is this latter version that is called by 
startMiniDFSCluster, causing the ceash under this profile.  What do you 
recommend we do?

> The HBase tests appear to leave around lots of cruft, namely graph.csv, 
> .graph.csv in the giraph folders and -ROOT-, simple_graph, hbase.version in 
> the user home directory. We should remove these (or better yet not create 
> them on first place).
