Amareshwari Sriramadasu commented on HADOOP-3182:
-------------------------------------------------
bq. In Task.moveTaskOutputs(...), is finalOutputPath a constant?
No, that is calculated from the parameters to moveTaskOutputs() and is called
recursively.
bq. Miscellaneous dirs: Current using the default permission, i.e. umask. What
is the correct permission for them???
The miscellaneous directories (submitJobdir/files, submitJobdir/archives,
submitJobdir/libjars) should have permissions same as submitJobDir. Patch
should address this one also.

> 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
