[GitHub] [doris] tiger-hcx opened a new issue, #16001: hive元数据相关

doris的版本是1.2.1.
场景：hudi数据写入的时候并同步元数据到hive，然后在doris中创建catalog，然后查询hudi的数据。
创建catalog：
CREATE CATALOG hive7 PROPERTIES (
'type'='hms',
'hive.metastore.uris' = 'thrift://ip:9083'
);
问题是：创建完catalog之后可以正常查询现有hudi的数据，但是新建一张hudi表的时候，新表元数据已经同步到hive，使用hive也可以正常查询hudi数据，但是使用doris查不到新建的这张表，需要重新新建一个catalog才能查到这张表。也就是doris连接hive元数据并不是实时同步的，只是同步了创建catalog的时候的hive元数据，这个问题如何解决呢？</div>

注意：
Hive 表 Schema 变更不会自动同步，需要在 Doris 中重建 Hive 外表。
