were wrong), so here comes to my questions:
1. How does AWS know how many map/reduce slot should be configured to each EC2
instance? Is it depends on the EC2 instance type (m1.large, m1.xlarge...)?2.
How it is charged? Nodes number * price per node per hour ?3. Is each node like
a single EC2
/hadoop-ec2 launch-cluster test-cluster 2
The command allows me to start a cluster with required nodes(no more than
20, correct me if i were wrong), so here comes to my questions:
1. How does AWS know how many map/reduce slot should be configured to each
EC2 instance? Is it depends on the EC2
launch-cluster command
start EMR node or common EC2 instance? Thanks a lot.
