Description

Users only care about their own business logic, do not care about the different implementation of stream and batch TableEnvironment.
From:

ExecutionEnvironment env = ...
BatchTableEnvironment tEnv = 
  TableEnvironment.getTableEnvironment(env);

To:

ExecutionEnvironment env = …
TableEnvironment tEnv = TableEnvironment.getTableEnvironment(env)
