Raghu Angadi commented on HADOOP-1873:
--------------------------------------
Owen says kerberos tickets are mostly renewable without private information.
Also, Owen suggested we should propegate the ticket through job conf file. This
sounds good to me. It implies we should be able to write and read objects as
entries in the conf file. I will try adding putWritable(), getWritable()
interface.
> User permissions for Map/Reduce

> HADOOP-1298 and HADOOP-1701 add permissions and pluggable security for DFS
> files and DFS accesses. Same users permission should work for Map/Reduce jobs
> as well.
> User persmission should propegate from client to map/reduce tasks and all the
> file operations should be subject to user permissions. This is transparent to
> the user (i.e. no changes to user code should be required).
