异常：fetch failed by table meta，版本1.0.26，tsdb.enable=true

[yueapple]

原sql是对表card_record 进行了两次alter操作
alter table card_record modify column customization_id bigint unsigned NOT NULL COMMENT '定制id' | 查看详情
alter table card_record modify column upgraded_customization_id bigint unsigned NOT NULL COMMENT '升级后定制id' | 查看详情

线上一次alter操作步骤是：

1. DROP TABLE IF EXISTS _card_record_gho
2. DROP TABLE IF EXISTS _card_record_del
3. create table yushitai_test._card_record_gho like yushitai_test.card_record
4. alter table yushitai_test._card_record_gho modify column customization_id bigint unsigned NOT NULL COMMENT 'ŚģöŚą∂id'
5. insert 数据到_card_record_gho
6. rename table yushitai_test.card_record to yushitai_test._card_record_del yushitai_test._card_record_gho to yushitai_test.card_record

手动设置位点到两条alter操作时间之前，重新消费时，当执行第二次alter 操作时，到步骤5时，会出现exception： fetch failed by table meta:yushitai_test._card_record_gho
