A static method to get the StreamExecutionEnvironment configuration merged with python dependency management configurations.

抛出:

InvocationTargetException

IllegalAccessException

NoSuchMethodException

getEnvironmentConfig

public static org.apache.flink.configuration.Configuration getEnvironmentConfig(org.apache.flink.streaming.api.environment.StreamExecutionEnvironment env)
                                                                         throws InvocationTargetException,

Get the private method StreamExecutionEnvironment.getConfiguration() by reflection recursively. Then access the method to get the configuration of the given StreamExecutionEnvironment.

抛出:

InvocationTargetException

IllegalAccessException

NoSuchMethodException

generateStreamGraphWithDependencies

public static org.apache.flink.streaming.api.graph.StreamGraph generateStreamGraphWithDependencies(org.apache.flink.streaming.api.environment.StreamExecutionEnvironment env,
                                                                                                   boolean clearTransformations)
                                                                                            throws IllegalAccessException,
                                                                                                   NoSuchMethodException,
                                                                                                   InvocationTargetException,

Generate a StreamGraph for transformations maintained by current StreamExecutionEnvironment, and reset the merged env configurations with dependencies to every OneInputPythonFunctionOperator. It is an idempotent operation that can be call multiple times. Remember that only when need to execute the StreamGraph can we set the clearTransformations to be True.

抛出:

IllegalAccessException

NoSuchMethodException

InvocationTargetException

NoSuchFieldException
