Allen Wittenauer commented on HADOOP-1873: ------------------------------------------ Yes, Kerberos tickets have timeouts. In fact, it is ultra-important that MR jobs be able to autorenew any renewable tickets they are passed. > User permissions for Map/Reduce > ------------------------------- > > Key: HADOOP-1873 > URL: https://issues.apache.org/jira/browse/HADOOP-1873 > Project: Hadoop > Issue Type: Improvement > Reporter: Raghu Angadi > Assignee: Raghu Angadi > > 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). -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
