Hello.
In Yarn Queue Manager, there is 4 queues defined :

but when we submit queries (using Hue or SAS Software to load data), only the default queue is used.
And we can go very high :

From what we undestand, Default queue is defined for using 20% of the cluster but can use up to 100%, so 70% is normal.

But our cluster is 365 GB / 15 vCores and some applications can use more :

7 / 7 / 6 / 5 / 3 vCores in the graph = 28 vCore !
How is it possible ?
Thanks for your help
