Nick Dimiduk commented on HBASE-7938:
-------------------------------------
In interest in exposure via integration tests is independence from the maven
for the target cluster's classpath. I want to be able to easily run some tests
on a real cluster, hence exposure via Tool interface. I don't think HBASE-7840
provides this isolation, but I'm prepared to be incorrect.

> We have existing unit tests for smoke-testing the packaged MR jobs, however
> they do not create a runtime environment that is true to running on a real MR
> cluster. This is particularly true in regard to classpaths (HBASE-7934) but
> also other static state (HBASE-4802). An integration test that can be pointed
> to run on a pseudo-distributed Hadoop deployed on localhost would find these
> kinds of problems.
