Dennis Kubes commented on HADOOP-1648:
--------------------------------------
I believe HADOOP-1622 will solve this issue without polluting hadoop scripts
with contrib specifics. The current patch for 1622 allow multiple resources
including directories, jars, files, etc. to be included in a map reduce job.
All resources are jared on the fly into a master job.jar that is deployed to
the hadoop cluster.
> Add contrib jars to general hadoop CLASSPATH

>
> A mapreduce job that depends on any of the hadoop contrib jars must bundle
> the contrib jar into its job jar or copy the contrib jar to the lib dir
> across the cluster because hadoop contribs are not on the general hadoop
> CLASSPATH. It would be an improvement if such as the included hbase
> mapreduce tasks did not require the running of this extra step.
