【产品名称】oceanbase
【产品版本】3.1.1
【问题描述】我是参考https://developer.aliyun.com/article/789554这个文章用docker搭建的oceanbase，建了一个表data_pool，有500W数据。想通过mysqldump命令导出数据。命令如下：
mysqldump -h127.0.0.1 -P2883 -u ‘root@obmysql’ -pabc123 --skip-triggers --databases test --tables data_pool -t >/data/dump_files/data_pool.sql;
执行完成后，data_pool.sql文件内容如下：
– MariaDB dump 10.19 Distrib 10.4.18-MariaDB, for Linux (x86_64)
–
– Host: 127.0.0.1 Database: test
– ------------------------------------------------------
– Server version 5.6.25

发现文件中没有任何数据。查看 observer.log，发现有异常：
