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 -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
