public void setAsContext()

setAsContext

public static void setAsContext(org.apache.flink.runtime.minicluster.JobExecutor jobExecutor,
                                int parallelism,
                                Collection<org.apache.flink.core.fs.Path> jarFiles,
                                Collection<URL> classPaths)

Sets the current ExecutionEnvironment to be a TestEnvironment. The test environment executes the given jobs on a Flink mini cluster with the given default parallelism and the additional jar files and class paths.

Parameters:

jobExecutor - The executor to run the jobs on

parallelism - The default parallelism

jarFiles - Additional jar files to execute the job with

classPaths - Additional class paths to execute the job with

setAsContext

public static void setAsContext(org.apache.flink.runtime.minicluster.JobExecutor jobExecutor,
                                int parallelism)

Sets the current ExecutionEnvironment to be a TestEnvironment. The test environment executes the given jobs on a Flink mini cluster with the given default parallelism and the additional jar files and class paths.

Parameters:

jobExecutor - The executor to run the jobs on

parallelism - The default parallelism

unsetAsContext

public static void unsetAsContext()
