Hello,
In Ambari main page, I noticed that it is writtent that Yarn only have 7G RAM available :
But I have a 4 nodes cluster with at least 11.5G Ram available
Here is my Yarn configurations :
Why Yarn doesn't have 28G RAM available ?
Regards.

@Arthur GREVIN it appears you only have one nodemanager deployed on those nodes. It is allocating 7 GB from that single node and that is why it is showing only that. You would need to deploy nodemanagers on the other 3 existing nodes.

what this widget is showing is from this configuration "Memory Node " which you have set as 7 gb. That is the only usable memory which can be allocated to Yarn containers in total. You can increase up to 11 gb. Hope I got your question correctly.
