Class InstanceTypeSpecification

    • Method Detail

      • instanceType

        public final String instanceType()

        The Amazon EC2 instance type, for example m3.xlarge.

        Returns:
        The Amazon EC2 instance type, for example m3.xlarge.

      • weightedCapacity

        public final Integer weightedCapacity()

        The number of units that a provisioned instance of this type provides toward fulfilling the target capacities defined in InstanceFleetConfig. Capacity values represent performance characteristics such as vCPUs, memory, or I/O. If not specified, the default value is 1.

        Returns:
        The number of units that a provisioned instance of this type provides toward fulfilling the target capacities defined in InstanceFleetConfig. Capacity values represent performance characteristics such as vCPUs, memory, or I/O. If not specified, the default value is 1.

      • bidPrice

        public final String bidPrice()

        The bid price for each Amazon EC2 Spot Instance type as defined by InstanceType. Expressed in USD.

        Returns:
        The bid price for each Amazon EC2 Spot Instance type as defined by InstanceType. Expressed in USD.

      • bidPriceAsPercentageOfOnDemandPrice

        public final Double bidPriceAsPercentageOfOnDemandPrice()

        The bid price, as a percentage of On-Demand price, for each Amazon EC2 Spot Instance as defined by InstanceType. Expressed as a number (for example, 20 specifies 20%).

        Returns:
        The bid price, as a percentage of On-Demand price, for each Amazon EC2 Spot Instance as defined by InstanceType. Expressed as a number (for example, 20 specifies 20%).

      • hasConfigurations

        public final boolean hasConfigurations()
        For responses, this returns true if the service returned a value for the Configurations property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • configurations

        public final List<Configuration> configurations()

        A configuration classification that applies when provisioning cluster instances, which can include configurations for applications and software bundled with Amazon EMR.

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

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasConfigurations() method.

        Returns:
        A configuration classification that applies when provisioning cluster instances, which can include configurations for applications and software bundled with Amazon EMR.

      • hasEbsBlockDevices

        public final boolean hasEbsBlockDevices()
        For responses, this returns true if the service returned a value for the EbsBlockDevices property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • ebsBlockDevices

        public final List<EbsBlockDevice> ebsBlockDevices()

        The configuration of Amazon Elastic Block Store (Amazon EBS) attached to each instance as defined by InstanceType.

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

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasEbsBlockDevices() method.

        Returns:
        The configuration of Amazon Elastic Block Store (Amazon EBS) attached to each instance as defined by InstanceType.

      • ebsOptimized

        public final Boolean ebsOptimized()

        Evaluates to TRUE when the specified InstanceType is EBS-optimized.

        Returns:
        Evaluates to TRUE when the specified InstanceType is EBS-optimized.

      • customAmiId

        public final String customAmiId()

        The custom AMI ID to use for the instance type.

        Returns:
        The custom AMI ID to use for the instance type.

      • priority

        public final Double priority()

        The priority at which Amazon EMR launches the Amazon EC2 instances with this instance type. Priority starts at 0, which is the highest priority. Amazon EMR considers the highest priority first.

        Returns:
        The priority at which Amazon EMR launches the Amazon EC2 instances with this instance type. Priority starts at 0, which is the highest priority. Amazon EMR considers the highest priority first.

      • hashCode

        public final int hashCode()
        Overrides:
        hashCode in class Object

      • equals

        public final boolean equals​(Object obj)
        Overrides:
        equals in class Object

      • toString

        public final String toString()
        Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
        Overrides:
        toString in class Object

      • getValueForField

        public final <T> Optional<T> getValueForField​(String fieldName,
