      Description

      When using any scheduler, you can use "yarn.scheduler.maximum-allocation-mb" to limit the overall size of a container. This applies globally to all containers and cannot be limited by queue or and is not scheduler dependent.

      The goal of this ticket is to allow this value to be set on a per queue basis.

      The use case: User has two pools, one for ad hoc jobs and one for enterprise apps. User wants to limit ad hoc jobs to small containers but allow enterprise apps to request as many resources as needed. Setting yarn.scheduler.maximum-allocation-mb sets a default value for maximum container size for all queues and setting maximum resources per queue with “maxContainerResources” queue config value.

      Suggested solution:

      All the infrastructure is already in the code. We need to do the following:

      • add the setting to the queue properties for all queue types (parent and leaf), this will cover dynamically created queues.
      • if we set it on the root we override the scheduler setting and we should not allow that.
      • make sure that queue resource cap can not be larger than scheduler max resource cap in the config.
      • implement getMaximumResourceCapability(String queueName) in the FairScheduler
      • implement getMaximumResourceCapability(String queueName) in both FSParentQueue and FSLeafQueue as follows
      • expose the setting in the queue information in the RM web UI.
      • expose the setting in the metrics etc for the queue.
      • Enforce the use of queue based maximum allocation limit if it is available, if not use the general scheduler level setting
        • Use it during validation and normalization of requests in scheduler.allocate, app submit and resource request
