Hi all, I am writing a program that uses YARN queue capacity data to estimate the resource limits, i.e. as current application, how much resource can be required at most, how much resource can be required at most without queue overcommit.
For example, I configure one yarn queue named 'queue1' in scheduler configuration file. Assume the application uses 20% resource of the whole cluster now. I find CapacityScheduler can provides queue1's runtime capacity, current capacity and maximum capacity; While FairScheduler provides only queue1's current capacity, and the current capacity value is set in field capacity. For example, Using CapacityScheduler, the report output looks like QueueName: queue1 Capacity: 50% CurrentCapacity:20% MaximumCapacity:100% Using FairScheduler, the report output looks like QueueName: queue1 Capacity:20% <------- in fact this value should be printed in the field CurrentCapacity. CurrentCapacity:0% MaximumCapacity:0% Is this a known issue ? Or is there a plan to improve FairScheduler to make queue report well filled? Any response is welcome, thank you all and looking forward to your response. Best, Yi
