All Implemented Interfaces:

@Generated("software.amazon.awssdk:codegen")
public final class VirtualCluster
extends Object
implements SdkPojo, Serializable, ToCopyableBuilder<VirtualCluster.Builder,VirtualCluster>

This entity describes a virtual cluster. A virtual cluster is a Kubernetes namespace that Amazon EMR is registered with. Amazon EMR uses virtual clusters to run jobs and host endpoints. Multiple virtual clusters can be backed by the same physical cluster. However, each virtual cluster maps to one namespace on an Amazon EKS cluster. Virtual clusters do not create any active resources that contribute to your bill or that require lifecycle management outside the service.

Method Detail

id

public final String id()

The ID of the virtual cluster.

Returns:

The ID of the virtual cluster.

name

public final String name()

The name of the virtual cluster.

Returns:

The name of the virtual cluster.

arn

public final String arn()

The ARN of the virtual cluster.

Returns:

The ARN of the virtual cluster.

state

public final VirtualClusterState state()

The state of the virtual cluster.

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

Returns:

The state of the virtual cluster.

See Also:

VirtualClusterState

stateAsString

public final String stateAsString()

The state of the virtual cluster.

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

Returns:

The state of the virtual cluster.

See Also:

VirtualClusterState

containerProvider

public final ContainerProvider containerProvider()

The container provider of the virtual cluster.

Returns:

The container provider of the virtual cluster.

createdAt

public final Instant createdAt()

The date and time when the virtual cluster is created.

Returns:

The date and time when the virtual cluster is created.

hasTags

public final boolean hasTags()

For responses, this returns true if the service returned a value for the Tags 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.

tags

public final Map<String,String> tags()

The assigned tags of the virtual cluster.

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 hasTags() method.

Returns:

The assigned tags of the virtual cluster.

toBuilder

public VirtualCluster.Builder toBuilder()

Specified by:

toBuilder in interface ToCopyableBuilder<VirtualCluster.Builder,VirtualCluster>

builder

public static VirtualCluster.Builder builder()

serializableBuilderClass

public static Class<? extends VirtualCluster.Builder> serializableBuilderClass()

hashCode

public final int hashCode()

Overrides:

hashCode in class Object

equals

public final boolean equals(Object obj)

Overrides:

equals in class Object

equalsBySdkFields

public final boolean equalsBySdkFields(Object obj)

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,
                                              Class<T> clazz)
