Hemanth Yamijala commented on HADOOP-3479:
------------------------------------------
The current list of configuration items, gleaned from HADOOP-3421, are the
following:
- Organization (org), identified by a string
-- Guarenteed capacity of resources per org.
-- Time limit within which resources redistributed from this org will be
reclaimed by it.
- Queue, identified by a string - org-name.queue-name should be unique
-- Organization to which queue belongs
-- Ordered list of users who can or cannot submit jobs to the queue
-- Default priority that will be assigned to all jobs submitted to this queue.
This is optional, and if it is not defined, it means the queue does not support
priorities.
-- Resource limit range per user.
Additional requirements that are related to configuration:
- All of these configuration items can be modified only by the admin.
- It should be possible to reflect modifications to these values without a JT
restart.
- There must be good default values for these items or they should be optional
so that users who do not want to setup organizations, multiple queues etc will,
ideally, not have to configure anything, or at worst, should configure very
little.
- Further the default values should also help in setting up new organizations,
queues, etc. For instance, we can define a global default priority value that
could apply to any newly created queue. And if required we should be able to
define a different value for this queue, which would override the global value.
