flink版本1.12.2 ，在交互式界面执行flink sql 连接hive操作时，出现连接拒绝异常，内容如下：
Flink SQL> use catalog myhive;
Flink SQL> show tables;
dim_kcl_customer_source_1h_all
mytest
Flink SQL> select * from dim_kcl_customer_source_1h_all limit 10;

[ERROR]
*Could not execute SQL statement. Reason:java.net.ConnectException:

*表能查出来，执行sql语句时遇到拒绝连接，在hive里面执行同样的sql能查到数据，请问一下这块出现的问题是什么原因导致的呢。该如何排查*
