I have few questions
This is absolutely true. Distcp dominates cp for large copies. On the
other hand cp dominates distcp for convenience.
In my own experience, I love cp when copying relatively small amounts of
data (10's of GB) where the available bandwidth of about a GB/s allows the
copy to complete in less

I have few questions regarding the usage of DistCP for copying files in the
same cluster.
1) Which one is better within a same cluster and what factors (like file
size etc) wouldinfluence the usage of one over te other?
2) when we run a cp command like below from a client node of the cluster

DistCP is a full blown mapreduce job (mapper only, where the mappers do a
fully parallel copy to the detsination).
CP appears (correct me if im wrong) to simply invoke the FileSystem and
issues a copy command for every source file.
I have an additional question: how is CP which is internal to a
internal parallel process and
will not copy files locally.
