Hi Ari, Hadoop jars should be autodetected from either HADOOP_HOME, or hadoopjars directory. For the agent side, you could remove the hadoop-0.18.3.jar from the hadoopjars directory to make data collection work with new version of hadoop. The current stopgap is messy because demux depends on hadoop-0.18.3 jar file. It was not the best approach to place hadoop-0.18.3 jar file in hadoopjars directory.
Short term, use HADOOP_HOME to control location of HADOOP jar file. Mid term, create individual RPM file which bundles the right hadoop jars. Long term, Upgrade demux pipeline to use hadoop 0.20.0+.
