JobFlowInstancesDetail

Empty constructor used to set properties independently even when a simple constructor is available

Instantiates JobFlowInstancesDetail with the parameterized properties

Gets and sets the property Ec2KeyName.

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

Gets and sets the property Ec2SubnetId.

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

Gets and sets the property HadoopVersion.

The Hadoop version for the cluster.

Gets and sets the property InstanceCount.

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.

Gets and sets the property InstanceGroups.

Details about the instance groups in a cluster.

Gets and sets the property KeepJobFlowAliveWhenNoSteps.

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

Gets and sets the property MasterInstanceId.

The Amazon EC2 instance identifier of the master node.

Gets and sets the property MasterInstanceType.

The Amazon EC2 master node instance type.

Gets and sets the property MasterPublicDnsName.

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.

Gets and sets the property NormalizedInstanceHours.

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.

Gets and sets the property Placement.

The Amazon EC2 Availability Zone for the cluster.

Gets and sets the property SlaveInstanceType.

The Amazon EC2 core and task node instance type.

Gets and sets the property TerminationProtected.

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.

Gets and sets the property UnhealthyNodeReplacement.

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