-----------------------------------
    Priority: Minor  (was: Major)

> Applications wait even if free executors are available
> ------------------------------------------------------

>                 Key: SPARK-10644
>                 URL: https://issues.apache.org/jira/browse/SPARK-10644
>             Project: Spark
>          Issue Type: Bug
>          Components: Scheduler
>    Affects Versions: 1.5.0
>         Environment: RHEL 6.5 64 bit
>            Reporter: Balagopal Nair
>            Priority: Minor
>
> Number of workers: 21
> Number of executors: 63
> Steps to reproduce:
> 1. Run 4 jobs each with max cores set to 10
> 2. The first 3 jobs run with 10 each. (30 executors consumed so far)
> 3. The 4 th job waits even though there are 33 idle executors.
> The reason is that a job will not get executors unless 
> the total number of EXECUTORS in use < the number of WORKERS
> If there are executors available, resources should be allocated to the pending job.
