Interface ClusterClientFactory<ClusterID>

All Known Implementing Classes:

AbstractContainerizedClusterClientFactory, StandaloneClientFactory

@Internal
public interface ClusterClientFactory<ClusterID>

A factory containing all the necessary information for creating clients to Flink clusters.

Method Summary

Modifier and Type	Method and Description
ClusterDescriptor<ClusterID>	createClusterDescriptor(org.apache.flink.configuration.Configuration configuration) Create a ClusterDescriptor from the given configuration.
default Optional<String>	getApplicationTargetName() Returns the option to be used when trying to execute an application in Application Mode using this cluster client factory, or an Optional.empty() if the environment of this cluster client factory does not support Application Mode.
ClusterID	getClusterId(org.apache.flink.configuration.Configuration configuration) Returns the cluster id if a cluster id is specified in the provided configuration, otherwise it returns null.
ClusterSpecification	getClusterSpecification(org.apache.flink.configuration.Configuration configuration) Returns the ClusterSpecification specified by the configuration and the command line options.
boolean	isCompatibleWith(org.apache.flink.configuration.Configuration configuration) Returns true if the current ClusterClientFactory is compatible with the provided configuration, false otherwise.

Method Detail

isCompatibleWith

boolean isCompatibleWith(org.apache.flink.configuration.Configuration configuration)

Returns true if the current ClusterClientFactory is compatible with the provided configuration, false otherwise.

createClusterDescriptor

ClusterDescriptor<ClusterID> createClusterDescriptor(org.apache.flink.configuration.Configuration configuration)

Create a ClusterDescriptor from the given configuration.

Parameters:

configuration - containing the configuration options relevant for the ClusterDescriptor

Returns:

the corresponding ClusterDescriptor.

getClusterId

@Nullable
ClusterID getClusterId(org.apache.flink.configuration.Configuration configuration)

Returns the cluster id if a cluster id is specified in the provided configuration, otherwise it returns null.

A cluster id identifies a running cluster, e.g. the Yarn application id for a Flink cluster running on Yarn.

Parameters:

configuration - containing the configuration options relevant for the cluster id retrieval

Returns:

Cluster id identifying the cluster to deploy jobs to or null

getClusterSpecification

ClusterSpecification getClusterSpecification(org.apache.flink.configuration.Configuration configuration)

Returns the ClusterSpecification specified by the configuration and the command line options. This specification can be used to deploy a new Flink cluster.

Parameters:

configuration - containing the configuration options relevant for the ClusterSpecification

Returns:

the corresponding ClusterSpecification for a new Flink cluster

getApplicationTargetName

default Optional<String> getApplicationTargetName()

Returns the option to be used when trying to execute an application in Application Mode using this cluster client factory, or an Optional.empty() if the environment of this cluster client factory does not support Application Mode.
