Default value not set for Configuration parameter mapreduce.job.local.dir
-------------------------------------------------------------------------
Key: MAPREDUCE-3975
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3975
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Affects Versions: 0.23.1, 0.23.2
Reporter: Eric Payne
Assignee: Eric Payne
Priority: Blocker
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.
