方法详细资料

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.

参数:

configuration - containing the configuration options relevant for the ClusterDescriptor

返回:

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.

参数:

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

返回:

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.

参数:

configuration - containing the configuration options relevant for the ClusterSpecification

返回:

the corresponding ClusterSpecification for a new Flink cluster
