Method Detail

masterInstanceType

public String masterInstanceType()

The Amazon EC2 master node instance type.

Returns:

The Amazon EC2 master node instance type.

masterPublicDnsName

public String masterPublicDnsName()

The DNS name of the master node.

Returns:

The DNS name of the master node.

masterInstanceId

public String masterInstanceId()

The Amazon EC2 instance identifier of the master node.

Returns:

The Amazon EC2 instance identifier of the master node.

slaveInstanceType

public String slaveInstanceType()

The Amazon EC2 slave node instance type.

Returns:

The Amazon EC2 slave node instance type.

instanceCount

public Integer 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.

Returns:

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.

instanceGroups

public List<InstanceGroupDetail> instanceGroups()

Details about the instance groups in a cluster.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

Returns:

Details about the instance groups in a cluster.

normalizedInstanceHours

public Integer normalizedInstanceHours()

An approximation of the cost of the cluster, represented in m1.small/hours. This value is incremented one time for every hour that 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.

Returns:

An approximation of the cost of the cluster, represented in m1.small/hours. This value is incremented one time for every hour that 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.

ec2KeyName

public String ec2KeyName()

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

Returns:

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

ec2SubnetId

public String ec2SubnetId()

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

Returns:

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

placement

public PlacementType placement()

The Amazon EC2 Availability Zone for the cluster.

Returns:

The Amazon EC2 Availability Zone for the cluster.

keepJobFlowAliveWhenNoSteps

public Boolean keepJobFlowAliveWhenNoSteps()

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

Returns:

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

terminationProtected

public Boolean 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.

Returns:

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.

hadoopVersion

public String hadoopVersion()

The Hadoop version for the cluster.

Returns:

The Hadoop version for the cluster.
