Hi [~jlowe] 

Were you referring to HADOOP-12857 for the hadoop-tools change? Just wanted to see what was done for hadoop-tools.

thanks

> [~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
