Amareshwari Sriramadasu commented on HADOOP-3182:

job-output-dir, job-history-dir and  job-temp-dir can have the permissions as 644.

bq. Are profile.getJobFile()).getParent() and new Path(conf.getSystemDir(), jobId) supposed
to be different?
Yes. It looks like they are the same directories.  One of the deletes can be removed. 
To be specific,       fs.delete(new Path(profile.getJobFile()).getParent(), true); can be

bq. What is the usage of FileUtil.fullyDelete? Is it the same as FileSystem.delete(path, recursive=true)?
Yes they are the same.

bq. job-dir/job.xml (aka jobconf, create-setPerm by JobClient; Should it be visible in JobTracker
webpage??? It is visible now.)
Yes. It should be visible :)

> JobClient creates submitJobDir with SYSTEM_DIR_PERMISSION ( rwx-wx-wx ) which causes
problem while sharing a cluster.
> Consider the case where userA starts jobtracker/tasktrackers and userB submits a job
to this cluster. When userB creates submitJobDir it is created with rwx-wx-wx which cannot
be read by tasktracker started by userA
