Summary: Create a Resource Manager Backend That Muliplexes
Key: OODT-764
URL: https://issues.apache.org/jira/browse/OODT-764
Project: OODT
Issue Type: New Feature
Components: resource manager
Reporter: Michael Starch
Priority: Minor
Fix For: 0.8
If a user wants to run various jobs using different technologies behind the
resource manager, then there needs to be a technology to choose between them.
For example (scheduler is the key component of the resource manager backend):
"mesos job" -> Mesos scheduler et. al.
"spark job -> Spark scheduler et. al.
"normal job" -> Standard resource manager scheduler et. al.
"torque job" -> Torque scheduler et. al.
The natural place to make the switch is based on the queue that that job is in.
Thus we can create a resource manager backend that multiplexes jobs based on
the queue that they are in.
This can be accomplished by using XML configuration to map queues to backend
sets, and create a custom set to multiplex between what is specified in XML.
The set must include the following:
Muxing components:
-Scheduler
-Batchmgr
-Monitor
Supporting components:
-Backend Manager - keeps track of children (Scheduler, Monitor, Batchmgr)
and which queue these sets are associated.
-Backend repository - to setup BackendManager via config
