The JobFlowInstancesDetail type exposes the following members

Constructors

NameDescription
Public Method JobFlowInstancesDetail() Empty constructor used to set properties independently even when a simple constructor is available
Public Method JobFlowInstancesDetail(string, string, int) Instantiates JobFlowInstancesDetail with the parameterized properties

Properties

NameTypeDescription
Public Property Ec2KeyName System.String Gets and sets the property Ec2KeyName.

The name of an Amazon EC2 key pair that can be used to ssh to the master node of job flow.

Public Property Ec2SubnetId System.String Gets and sets the property Ec2SubnetId.

For job flows launched within Amazon Virtual Private Cloud, this value specifies the identifier of the subnet where the job flow was launched.

Public Property HadoopVersion System.String Gets and sets the property HadoopVersion.

The Hadoop version for the job flow.

Public Property InstanceCount System.Int32 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 slave node. If the value is greater than 1, one instance is the master node and all others are slave nodes.

Public Property InstanceGroups System.Collections.Generic.List<Amazon.ElasticMapReduce.Model.InstanceGroupDetail> Gets and sets the property InstanceGroups.

Details about the job flow's instance groups.

Public Property KeepJobFlowAliveWhenNoSteps System.Boolean Gets and sets the property KeepJobFlowAliveWhenNoSteps.

Specifies whether the job flow should terminate after completing all steps.

Public Property MasterInstanceId System.String Gets and sets the property MasterInstanceId.

The Amazon EC2 instance identifier of the master node.

Public Property MasterInstanceType System.String Gets and sets the property MasterInstanceType.

The Amazon EC2 master node instance type.

Public Property MasterPublicDnsName System.String Gets and sets the property MasterPublicDnsName.

The DNS name of the master node.

Public Property NormalizedInstanceHours System.Int32 Gets and sets the property NormalizedInstanceHours.

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

Public Property Placement Amazon.ElasticMapReduce.Model.PlacementType Gets and sets the property Placement.

The Amazon EC2 Availability Zone for the job flow.

Public Property SlaveInstanceType System.String Gets and sets the property SlaveInstanceType.

The Amazon EC2 slave node instance type.

Public Property TerminationProtected System.Boolean 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.
