> I'm seeing the same failure as MAPREDUCE-3462 in downstream projects running against
a recent build of branch-23. MR-3462 modified the tests rather than fixing the framework.
In that jira Ravi mentioned "I'm still ignorant of the change which made the tests start to
fail. I should probably understand better the reasons for that change before proposing a more
generalized fix." Let's figure out the general fix (rather than require all projects to set
mapreduce.job.hdfs-servers in their conf we should fix this in the framework). Perhaps we
should not default this config to "$fs.default.name"?
