Hi everybody,

We are going to change the Yarn scheduler in a bit, moving from Fair to Capacity. More info in https://wikitech.wikimedia.org/wiki/Analytics/Systems/Cluster/Hadoop#Queues

It shouldn't impact ongoing jobs, but there will probably be some tuning/adjustment to do during the next few days. If you see any weird behavior please ping us or contact us in T277062.

A gift for your patience: this change will allow users to select hadoop nodes with GPUs when launching jobs :) (we have 6, running the same GPUs as stat100[5,8]).
