Method Detail

name

public String name()

Friendly name given to the instance group.

Returns:

Friendly name given to the instance group.

market

public MarketType market()

MarketType

marketAsString

public String marketAsString()

Market type of the EC2 instances used to create a cluster node.

If the service returns an enum value that is not available in the current SDK version, market will return MarketType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from marketAsString().

Returns:

Market type of the EC2 instances used to create a cluster node.

public InstanceRoleType instanceRole()

The role of the instance group in the cluster.

If the service returns an enum value that is not available in the current SDK version, instanceRole will return InstanceRoleType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from instanceRoleAsString().

Returns:

The role of the instance group in the cluster.

See Also:

InstanceRoleType

instanceRoleAsString

public String instanceRoleAsString()

The role of the instance group in the cluster.

If the service returns an enum value that is not available in the current SDK version, instanceRole will return InstanceRoleType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from instanceRoleAsString().

Returns:

InstanceRoleType

bidPrice

public String bidPrice()

The maximum Spot price your are willing to pay for EC2 instances.

An optional, nullable field that applies if the MarketType for the instance group is specified as SPOT. Specify the maximum spot price in USD. If the value is NULL and SPOT is specified, the maximum Spot price is set equal to the On-Demand price.

Returns:

The maximum Spot price your are willing to pay for EC2 instances.

An optional, nullable field that applies if the MarketType for the instance group is specified as SPOT. Specify the maximum spot price in USD. If the value is NULL and SPOT is specified, the maximum Spot price is set equal to the On-Demand price.

instanceType

public String instanceType()

The EC2 instance type for all instances in the instance group.

Returns:

The EC2 instance type for all instances in the instance group.

instanceCount

public Integer instanceCount()

Target number of instances for the instance group.

Returns:

Target number of instances for the instance group.

configurations

public List<Configuration> configurations()

Amazon EMR releases 4.x or later.

The list of configurations supplied for an EMR cluster instance group. You can specify a separate configuration for each instance group (master, core, and task).

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

Returns:

Returns:

EBS configurations that will be attached to each EC2 instance in the instance group.

autoScalingPolicy

public AutoScalingPolicy autoScalingPolicy()

An automatic scaling policy for a core instance group or task instance group in an Amazon EMR cluster. The automatic scaling policy defines how an instance group dynamically adds and terminates EC2 instances in response to the value of a CloudWatch metric. See PutAutoScalingPolicy.

Returns:

An automatic scaling policy for a core instance group or task instance group in an Amazon EMR cluster. The automatic scaling policy defines how an instance group dynamically adds and terminates EC2 instances in response to the value of a CloudWatch metric. See PutAutoScalingPolicy.
