> 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.
