Steve Loughran commented on HADOOP-13865:
-----------------------------------------
I have mixed feelings here. I like bits on the CLI, and indeed think we
(hortonworks) stick some more of the hadoop-aws and hadoop-azure stuff on our
CP, albeit by copying them to somewhere on that path
At the same time, the fact that we bleed so much of our CP into downstream
programs makes it a dangerous minefield about updating anything; the size of
that CP means that it's inevitable that we break things whenever we do —so are
trapped into shipping out of date stuff (Guava, Jackson) to minimise this pain
(see HADOOP-9991).
Looking at your specific problem: distcp runs on the `hadoop distcp` command.
Why exactly were you trying to use it from hive?
