sql-client batch 模式执行报错

Wed, 06 Mar 2019 17:23:33 -0800 

我在sql-client提交任务：


create table csv_source1(
id varchar,
name varchar
) with (
type ='csv',
path = '/Users/IdeaProjects/github/apache-flink/build-target/bin/test1.csv'
);




create table csv_sink(
id varchar,
name varchar
) with (
type ='csv',
path = '/Users/IdeaProjects/github/apache-flink/build-target/bin/test4.csv'
);


insert into csv_sink  select t1.name,t1.id from csv_source1 t1




错误是org.apache.flink.table.api.TableEnvironment这个类1300行空指针，用execution 
batch模式不行，用execution streaming模式是可以的。请问下才能batch模式执行这个sql?
