    • Type: Bug
    • Status: Resolved
    • Priority: Minor
    • Resolution: Not A Problem
    • Affects Version/s: 1.5.0
    • Fix Version/s: None
    • Component/s: Scheduler
    • Labels:
      None
    • Environment:

      RHEL 6.5 64 bit

    • Target Version/s:

      Description

      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.
