Limit application resource reservation on nodes for non-node/rack specific requests

    Details

    • Type: Bug
    • Status: Resolved
    • Priority: Major
    • Resolution: Fixed
    • Affects Version/s: None
    • Fix Version/s: 2.8.0, 3.0.0-alpha1
    • Component/s: fairscheduler
    • Labels:
      None

      Description

      I has been noticed that for off-switch requests, the FairScheduler reserves resources on all nodes. This could lead to the entire cluster being unavailable for all other applications.

      Ideally, the reservations should be on a configurable number of nodes, default 1.
