Jason Lowe commented on MAPREDUCE-6413:
---------------------------------------

Thanks for picking this up, [~zxu].

Do we even need to bother with HDFS?  MiniDFSCluster makes every test it's a part of noticeably
slower, and I'm not seeing why we need it here.  I got the impression "hdfs://testcluster"
was just some bogus input anyway, so can we just use something "file:///" instead?  This is
the default, and we're already relying on other defaults like mapreduce.framework.name=local.

As an aside, I'd personally prefer we explicitly set the values we expect to be using in unit
tests, even if they're the default, for two reasons: 1) document the setup/reqs of the test
and 2) protect the test from custom confs appearing in HADOOP_CONF_DIR when the test is run.
