Subject [jira] [Commented] (MAPREDUCE-3975) Default value not set for Configuration parameter mapreduce.job.local.dir
Date Tue, 06 Mar 2012 23:41:57 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3975?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13223819#comment-13223819
] 

Arun C Murthy commented on MAPREDUCE-3975:
------------------------------------------

bq. I think that it is fine to have them in different base directories, if it becomes a problem
in practice because tasks are trying to share data with each other, then it can be fixed then.

> 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.
