I started up a cluster on EC2 (using the provided scripts) and specified a different instance type for the master and the the worker nodes. The cluster started fine, but when I looked at the cluster (via port 8080), it showed that the amount of memory available to the worker nodes did not match the instance type I had specified. Instead, the amount of memory for the worker nodes matched the master node. I did verify that the correct instance types had been started for the master and worker nodes.
Curious as to whether this is expected behavior or if this might be a bug? Thanks. Darin.
