Creates the JobGraph corresponding to the provided Pipeline.

Parameters:

pipeline - the pipeline whose job graph we are computing.

configuration - the configuration with the necessary information such as jars and classpaths to be included, the parallelism of the job and potential savepoint settings used to bootstrap its state.

userClassloader - the classloader which can load user classes.

Returns:

the corresponding JobGraph.

Throws:

MalformedURLException

notifyJobStatusListeners

Notify the DefaultJobCreatedEvent to job status changed listeners.

Parameters:

pipeline - the pipeline that contains lineage graph information.

executionPlan - executionPlan that contains job basic info

listeners - the list of job status changed listeners
