Jobs Are Dropped When Queue Size Is Full
----------------------------------------
Key: OODT-439
URL: https://issues.apache.org/jira/browse/OODT-439
Project: OODT
Issue Type: Bug
Components: resource manager
Affects Versions: 0.3, 0.4
Reporter: Michael Cayanan
Priority: Minor
Fix For: 0.5
When the queue has reached the max queue size, a message is logged by the
Scheduler saying there is a Job Queue Exception adding a job to the queue, and
then the job is dropped.
The following case will produce the issue:
1) queue is full
2) scheduler pops job from queue and begins trying to find a node for job
3) queue now has 1 open slot
4) another job is given to the resource manager and is placed in the queue
5) queue is now full again
6) scheduler fails to schedule popped job
7) scheduler pushes job back into the queue
8) queue is full so exception is thrown and job is lost
The job needs to get re-queued in this case.
