我们计划从oceanbase中导出某个租户下某个数据库的表结构和数据，用mydumper执行导出报错，基于代理2883和直连2881导出都报错，报错详情：

[root@dbserver test]# mydumper -h 192.168.0.33 -P 2883 -u ‘edudiagnose@tt_edu’ -B edu_dw --no-data -o /home/test/schema2

** (mydumper:41270): WARNING **: Set session failed: /*!80003 SET SESSION information_schema_stats_expiry = 0 */

所以请教下，oceanbase支持mydumper导出数据库吗（租户模式是mysql）？这个错误怎么解决呢，谢谢
