dumpling导出数据报错二

第一个报错
[errorVerbose="Error 1146: Table ‘information_schema.placement_policies’ doesn’t exist
sql: select distinct policy_name from
看起来6.1的dumpling会去查information_schema.placement_policies用于判断是否用了放置策略。5.1还没有这个字典表。
第二个报错
[“cannot execute query”] [retryTime=1] [sql=“SELECT id FROM yifu_produce.produce_param TABLESAMPLE REGIONS() ORDER BY id”] [args=null] [error=“sql: SELECT id FROM yifu_produce.produce_param TABLESAMPLE REGIONS() ORDER BY id, args: : invalid connection”]
和这个帖子很像,可以参考下
