Nick Dimiduk commented on HBASE-7938:
-------------------------------------

Yeah, I like how that test is broken out. However, I think having a main per test and also being able to run from IntegrationTestsDriver is redundant. The reality is, the runtime classpath for these tests is a little bit prickly (see HBASE-7971) and while it would be great for a user to be able to run the IT suite as a smoke-test of an upgrade or fresh install, we don't exactly make that easy right now.

My thinking is that a test would configure itself via the run method, no additional arguments necessary. The biggest thing is hooking into Hadoop's GenericOptionsParser in order to set up an external -conf and any -D overrides the user wants to impose.

> 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.
