Hi Roger, I've seen unbalanced container assignment across hosts but never one being maxed out before any others get any containers. So I'd look to the YARN config to start with.
I believe though there will be a risk of this type of thing until YARN implements anti-affinity: https://issues.apache.org/jira/browse/YARN-1042 But as said above, maxing out a host at a time does sound odd to me.

I'm using Capacity Scheduler with a default config. Is there a way to make it "round-robin" among the available machines? Thanks, Roger ----- No virus found in this message.
