Sean Busbey commented on HBASE-18953:
-------------------------------------
Copying my comment from HADOOP-14178:
{quote}
Maybe in the future? Right now HBase's dependency on Hadoop is kind of messy
for a few reasons.
# we have to keep working on top of Hadoop 2.x and Hadoop 3.x. We mostly have
this abstracted.
# we have parts of HBase that make use of Hadoop internals such that we can't
currently move all of the Hadoop-3 build version on to the client artifacts
# The parts of HBase that use Hadoop internals are currently all mixed up with
parts that are proper downstream consumers, so we can't even e.g. isolate the
problem parts and then avoid mockito there.

The hadoop client artifacts have to be used to the exclusion of the
non-downstream facing ones. you can't leave in e.g. hadoop-common. I have a
branch sitting around somewhere from the last time I tried to do this via
either moving our internal Hadoop usage to different modules or copying source
into our tree. It was a morass, but things are considerably better now in our
codebase.
If you're interested in digging into this [~tedyu], I'd be willing to rebase my
prior attempt and note where it looks broken to give you a starting point. Fair
warning though, it's probably still a good deal of work.

> Over HADOOP-14178 , [~bharatviswa] suggested using hadoop shaded jars for
> hadoop-3 since Hadoop client run time has all 3rd party dependencies of
> Hadoop.
> This would avoid issues starting mini dfs cluster.
