What does "% of Queue" refer to in the hadoop yarn UI

Question

I regularly schedule spark applications via yarn and use the yarn web UI in order to track the applications. However, I haven't been able to figure out what this column in the applications table refers to:

I can't find any information about it online. Does anyone know what "% of Queue" means in this context?

Answer 1

Thats "the percentage of resources of the queue that the app is using" [source].

%-age over a hundred can occur, for example, if you're using FairScheduler, due to the difference in queue's Instantaneous vs Steady fair share.
