I created a job like you said and ran it on Hadoop 1 and Hadoop 2 with and
without setting the working dir. The behavior is the same in both Hadoop 1 and
Hadoop 2: without setting the working dir, it resolves a relative path to the
homedir; with setting the working dir, it resolves a relative path to that dir
(even in Hadoop 1). So no behavioral change here :)

While the patch looks good, we may have introduced a behavioral change in the
{{setOutputPath()}} method.
In Hadoop 1, {{setOutputPath()}} sets whatever path it is received in the conf,
without any modification.
In Hadoop 2, {{setOutputPath()}} makeQualified-s the received path and then
sets it in the conf.
This means that in Hadoop 1 a relative path will always resolved to the homedir
while in Hadoop 2 a relative path will be resolved to the working dir (by
default set to the homedir).
Can we please verify this hypothesis? This could be done by having a simple MR
job where in the submission we set (or not) the workingdirectory in the FS, and
use a relative path for the output dir. Then run the job once setting
workingdir to /tmp, once not setting it at all. Run this in Hadoop 1 and in
Hadoop 2. Find out where the job output ends in all cases. If different, we
need to decide if we want to revert to Hadoop 1 behavior or not.

I just ran all of the tests under {{hadoop-mapreduce-project}} successfully.
I also just checked where those two methods are used and there's no issues
because:
1) Whenever {{checkOutputSpecs}} is used, the code handles an {{IOException}}
instead of either of the two types of {{FileAlreadyExistsException}}, and both
types of {{FileAlreadyExistsException}} inherit from {{IOException}}
2) Whenever {{setOutputPath}} is used, there's always other method calls that
can throw {{IOException}}s anyway

Thanks Robert. The patch looks good, the tests in particular. I am surprised
these changes didn't result in other changes due to calls to the methods whose
signature the patch modifies. Given Jenkins doesn't complain, it should be
okay. Do you want to double-check just in case.
