Ravi Prakash commented on HADOOP-10738:
---------------------------------------

I'm not sure Siqi Li is active anymore Arpit. I suspect the way most people use 
distcp is in an [oozie 
action|https://oozie.apache.org/docs/4.0.0/DG_DistCpActionExtension.html]. I 
suspect they want to specify a single xml file where they can have all the 
configuration for a source-destination pair. The alternative is to have the 
exact set of parameters copy-pasted in multiple workflows (which if changed 
then has to be updated in all workflows). Please correct me if I'm wrong 
[~ferhui] . Other users?

> For now, the configuration of distcp resides in hadoop-distcp.jar. This makes 
> it difficult to adjust the configuration dynamically.
