> mapreduce.job.local.dir (formerly job.local.dir in 0.20) is not set by default. This
is a regression from 0.20.205.
> In 0.20.205, JobLocalizer.createWorkDir() constructs the "$mapred.local.dir/taskTracker/$user/jobcache/$jobid/work"
path based on $user and $jobid, and then sets TaskTracker.JOB_LOCAL_DIR in the job's JobConf.
> So far, I haven't found where this is done in 0.23. It could be that this is what should
be done by LocalJobRunner.setupChildMapredLocalDirs(), but I am still investigating.
