Hi, I have a cluster with 4 nodes (NameNode: 8Gb RAM, 3 Data nodes with 4GB RAM).
In the Ressource Manager UI i'm getting only one Active Node:
Is this Normal ?
You have to check on how many node Node Mangers are installed, the info can be checked on Ambari Dashboard -> YARN
I assume it is one and that is the reason you see only one Active Node

Yep, Only one .. Can I add new ones ?
Okay, I installed the NodeManger on the 3 remaining nodes and I have now all the nodes active.
