> Issue Type: Sub-task
> Affects Versions: trunk
> Reporter: Robert Kanter

>
> In doing OOZIE-1722, we had not not add support for the DistCp action because
> there wasn't a good clean way to set the {{mapreduce.job.tags}} property on
> the job launched by DistCp that would work between all versions of Hadoop.
> The best solution would be to switch our version of Hadoop 1 to Hadoop 1.2.1
> (OOZIE-1613), which would make DistCp v2 available in Hadoop 1. The
> signatures of DistCp's constructor (where we can pass the tags property in a
> Configuration) should then be same. We can then duplicate what
> DistCp.main(...) does.
> A more immediate solution would involve some ugly reflection based on
> different versions of Hadoop.
