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