我使用java jdbc连接starrocks 3.2.6版本数据库，在使用insert into files方法导出数据文件到hdfs上时，偶发性报错：com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure The last packet successfully received from the server was 8,473,558 milliseconds ago. The last packet sent successfully to the server was 7,200,765 milliseconds ago.
有大佬知道怎么回事吗？我是在程序中反复执行insert into files操作导出表的各个分区，当文件特别大时会报这个错
