Vivek Ratan commented on HADOOP-4428:
-------------------------------------
Summarizing the details:
We have two config values for the scheduler, regarding the number of
simultaneous jobs that can be initialized: #jobs/user and #jobs/queue. These
are optional settings in the scheduler's config file. Their default values are
3 and 10 respectively.
If these limits are met, or all jobs in a queue have been looked at, and no
task has been found, the scheduler looks at the next queue.
HADOOP-4471 has been created to deal with the sorting of running jobs.
