Review comment:
consider the following user table program:
val env = ExecutionEnvironment.getExecutionEnvironment()
val tableEnv = BatchTableEnvironment.create(env, config)
env.registerCachedFile("/tmp/cache", "my_cache")
val input = env.fromElements(...)...
tEnv.fromDataSet(input)...
tEnv.execute() // will generate plan through PlanGenerator in this method
If we do not expose this method, the generated plan does not contain the
cache files registered in DataSet program.(which can be converted to Table
through `BatchTableEnvironment.fromDataSet` method)
