> [~jlowe] had a good observation about the user classpath getting extra jars in hadoop
2.x brought in with TSv2.  If users start picking up Hadoop 2,x's version of HBase jars instead
of the ones they shipped with their job, it could be a problem.
> So when TSv2 is to be used in 2,x, the hbase related jars should come into only the NM
classpath not the user classpath.
> Here is a list of some jars

> commons-csv-1.0.jar
> commons-el-1.0.jar
> commons-httpclient-3.1.jar
