>            Reporter: Jark Wu

> I tried the following test, and the printed node parallelism in json plan is not 5. 
> {code:scala}
>   @Test
>   def testExplainAndExecuteSingleSink(): Unit = {
>     val env = TableEnvironmentImpl.create(settings)
>     val conf = new Configuration();
>     conf.setInteger("parallelism.default", 5)
>     conf.setInteger("taskmanager.numberOfTaskSlots", 1)
>     env.getConfig.addConfiguration(conf)
>     TestTableSourceSinks.createCsvTemporarySinkTable(
>       env, new TableSchema(Array("first"), Array(STRING)), "MySink1")
>     TestTableSourceSinks.createPersonCsvTemporaryTable(env, "MyTable")
>     println(env.explainSql("insert into MySink1 select first from MyTable",
>       ExplainDetail.JSON_EXECUTION_PLAN))
> }
> {code}
> I think the bug is because TableEnvironemnt#explain will not invoke  {{PlannerBase#translate(modifyOperations: util.List[ModifyOperation])}} where we configure the configuration into underlying {{StreamExecutionEnvironment}}.
