我正在尝试从超集访问 Athena，连接成功并且可以看到 SQL 编辑器中的所有模式和表（启用在 SQL 实验室中公开此数据库）。

在 SQL 编辑器上加载元数据时，它返回以下错误：

ERROR OCCURRED WHILE FETCHING TABLE METADATA

在 Athena 上，它运行以下查询

SELECT table_schema,
     table_name,
     column_name,
     data_type,
     is_nullable,
     column_default,
     ordinal_position,
     comment
FROM information_schema.columns

此查询在 athena 上返回以下错误。

HIVE_INVALID_METADATA: com.facebook.presto.hive.DataCatalogException: 
Error: : expected at the position 16 of 'struct<FULL_BEAM0.2000:struct<DiskHU:string,HUFlatness:double,PhantomHU:double,PhantomSNR:double,ResolutionLength:double,ResolutionMTF:string,dateTime:string,examID:string,jobID:string,version:string>,
FULL_BEAM-0.4000:struct<DiskHU:string,HUFlatness:double,PhantomHU:double,PhantomSNR:double,ResolutionLength:double,ResolutionMTF:string,dateTime:string,examID:string,jobID:string,version:string>>' 
but '-' is found. (Service: null; Status Code: 0; Error Code: null; Request ID: null)

尝试访问源下的显示记录 - > 表，列表列选项卡为空，因此当我单击刷新元数据时，我收到 500 - 内部服务器错误。错误的堆栈跟踪如下所示：

任何人都知道此错误的解决方案。

谢谢
