> On 0.94, ExportSnapshot uses "hbase.tmp.dir" as the job's staging directory on hdfs.
However, "hbase.tmp.dir" is by definition a local directory, thus should not be used as an
hdfs directory for the job. 
> Trunk uses JobUtil.getStagingDir() which gets the staging dir from JobSubmissionFiles
class in Hadoop, so trunk is fine. 
> We've discovered this since it fails the test on windows, but this is not windows-specific
as per above (like specifying hbase.tmp.dir as /var/hbase/tmp/ etc)
