Chesnay Schepler updated FLINK-34422:
-------------------------------------
    Description: 
BatchTestBase sets up a table environment in instance fields, which runs before 
the BeforeEachCallback from the MiniClusterExtension has time to run.
As a result the table environment internally creates a local stream 
environment, due to which _all_ test extending the BatchTestBase are spawning 
separate mini clusters for every single job.
