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. -- This message is automatically generated by JIRA.
