Class VirtualCluster
- All Implemented Interfaces:
Serializable
,SdkPojo
,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 Details
-
id
The ID of the virtual cluster.
- Returns:
- The ID of the virtual cluster.
-
name
The name of the virtual cluster.
- Returns:
- The name of the virtual cluster.
-
arn
The ARN of the virtual cluster.
- Returns:
- The ARN of the virtual cluster.
-
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 returnVirtualClusterState.UNKNOWN_TO_SDK_VERSION
. The raw value returned by the service is available fromstateAsString()
.- Returns:
- The state of the virtual cluster.
- See Also:
-
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 returnVirtualClusterState.UNKNOWN_TO_SDK_VERSION
. The raw value returned by the service is available fromstateAsString()
.- Returns:
- The state of the virtual cluster.
- See Also:
-
containerProvider
The container provider of the virtual cluster.
- Returns:
- The container provider of the virtual cluster.
-
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 theisEmpty()
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
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
Description copied from interface:ToCopyableBuilder
Take this object and create a builder that contains all of the current property values of this object.- Specified by:
toBuilder
in interfaceToCopyableBuilder<VirtualCluster.Builder,

- a builder for type T

equalsBySdkFields
Description copied from interface:SdkPojo
Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in anSdkPojo
class, and is generated based on a service model.If an
SdkPojo
class does not have any inherited fields,equalsBySdkFields
andequals
are essentially the same.- Specified by:
equalsBySdkFields
in interfaceSdkPojo
- Parameters:
obj
- the object to be compared with- Returns:
- true if the other object equals to this object by sdk fields, false otherwise.
-
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. -
