The name of an Amazon EC2 key pair that can be used to connect to the master node using SSH.

Link copied to clipboard

For clusters launched within Amazon Virtual Private Cloud, this is the identifier of the subnet where the cluster was launched.

Link copied to clipboard

The Hadoop version for the cluster.

Link copied to clipboard

The number of Amazon EC2 instances in the cluster. If the value is 1, the same instance serves as both the master and core and task node. If the value is greater than 1, one instance is the master node and all others are core and task nodes.

Details about the instance groups in a cluster.

Specifies whether the cluster should remain available after completing all steps.

Link copied to clipboard

The Amazon EC2 instance identifier of the master node.

Link copied to clipboard

The Amazon EC2 master node instance type.

Link copied to clipboard

The DNS name of the master node. If the cluster is on a private subnet, this is the private DNS name. On a public subnet, this is the public DNS name.

Link copied to clipboard

An approximation of the cost of the cluster, represented in m1.small/hours. This value is increased one time for every hour that an m1.small instance runs. Larger instances are weighted more heavily, so an Amazon EC2 instance that is roughly four times more expensive would result in the normalized instance hours being increased incrementally four times. This result is only an approximation and does not reflect the actual billing rate.

Link copied to clipboard

The Amazon EC2 Availability Zone for the cluster.

Link copied to clipboard

The Amazon EC2 core and task node instance type.

Link copied to clipboard

Specifies whether the Amazon EC2 instances in the cluster are protected from termination by API calls, user intervention, or in the event of a job-flow error.

Link copied to clipboard

Indicates whether Amazon EMR should gracefully replace core nodes that have degraded within the cluster.
