Queue ACLs should be refreshed without requiring a restart of the job tracker
-----------------------------------------------------------------------------
Key: HADOOP-5396
URL: https://issues.apache.org/jira/browse/HADOOP-5396
Project: Hadoop Core
Issue Type: Improvement
Components: mapred
Reporter: Hemanth Yamijala
In large shared deployments of the M/R clusters, it is normal that new users
will periodically want to get access to some queues on the M/R framework.
Requiring a JT restart for each such change is operationally inconvenient and
seems an overkill. There should be a way for updating ACLs with new users
without requiring a JT restart.
