JobFlowInstancesDetail
Description
Specify the type of Amazon EC2 instances to run the job flow on.
Contents
| Name | Description |
|---|---|
Ec2KeyName
|
The name of an Amazon EC2 key pair that can be used to ssh to the master node of job flow. Type: String Length constraints: Minimum length of 0. Maximum length of 256. |
Ec2SubnetId
|
For job flows launched within Amazon Virtual Private Cloud, this value specifies the identifier of the subnet where the job flow was launched. Type: String Length constraints: Minimum length of 0. Maximum length of 256. |
HadoopVersion
|
Specifies the Hadoop version for the job flow. Type: String Length constraints: Minimum length of 0. Maximum length of 256. |
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. Type: Integer |
InstanceGroups
|
Details about the job flow's instance groups. Type: InstanceGroupDetail list |
KeepJobFlowAliveWhenNoSteps
|
Specifies whether or not the job flow should terminate after completing all steps. Type: Boolean |
MasterInstanceId
|
The Amazon EC2 instance identifier of the master node. Type: String Length constraints: Minimum length of 0. Maximum length of 10280. |
MasterInstanceType
|
The Amazon EC2 master node instance type. Type: String Length constraints: Minimum length of 1. Maximum length of 256. |
MasterPublicDnsName
|
The DNS name of the master node. Type: String Length constraints: Minimum length of 0. Maximum length of 10280. |
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. Type: Integer |
Placement
|
Specifies the Amazon EC2 Availability Zone for the job flow. Type: PlacementType |
SlaveInstanceType
|
The Amazon EC2 slave node instance type. Type: String Length constraints: Minimum length of 1. Maximum length of 256. |
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. Type: Boolean |
