A description of the Amazon EC2 instance running the job flow.
Declaration Syntax| C# |
public class JobFlowInstancesConfig
Members| All Members | Constructors | Methods | Properties | ||
| Icon | Member | Description |
|---|---|---|
 | JobFlowInstancesConfig()()()() | Initializes a new instance of the JobFlowInstancesConfig class |
 | Ec2KeyName |
Specifies the name of the Amazon EC2 key pair that can be used to ssh to the master node as the user called "hadoop."
Constraints: |
| Ec2SubnetId |
To launch the job flow in Amazon Virtual Private Cloud (Amazon VPC), set this parameter to the identifier of the Amazon VPC subnet where you
want the job flow to launch. If you do not specify this value, the job flow is launched in the normal Amazon Web Services cloud, outside of
an Amazon VPC. Amazon VPC currently does not support cluster compute quadruple extra large (cc1.4xlarge) instances. Thus you cannot specify
the cc1.4xlarge instance type for nodes of a job flow launched in a Amazon VPC.
Constraints: |
| Equals(Object) | (Inherited from Object.) |
| GetHashCode()()()() | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType()()()() | Gets the type of the current instance. (Inherited from Object.) |
| HadoopVersion |
Specifies the Hadoop version for the job flow. Valid inputs are "0.18", "0.20", or "0.20.205". If you do not set this value, the default of
0.18 is used, unless the AmiVersion parameter is set in the RunJobFlow call, in which case the default version of Hadoop for that AMI
version is used.
Constraints: |
| InstanceCount |
The number of Amazon EC2 instances used to execute the job flow.
|
| InstanceGroups |
Configuration for the job flow's instance groups.
|
| KeepJobFlowAliveWhenNoSteps |
Specifies whether the job flow should terminate after completing all steps.
|
| MasterInstanceType |
The EC2 instance type of the master node.
Constraints: |
| Placement |
Specifies the Availability Zone the job flow will run in.
|
| SlaveInstanceType |
The EC2 instance type of the slave nodes.
Constraints: |
| TerminationProtected |
Specifies whether to lock the job flow to prevent the Amazon EC2 instances from being terminated by API call, user intervention, or in the
event of a job flow error.
|
| ToString()()()() | Returns a string that represents the current object. (Inherited from Object.) |
