Amazon QuickSight 中搭配 Athena 使用 AWS Glue 時資料表不相容
如果您在將 Athena 中的 AWS Glue 資料表與 Amazon QuickSight 搭配使用時發生錯誤，可能是因為您缺少一些中繼資料。請依照這些步驟來了解您的資料表是否沒有 Amazon QuickSight 讓 Athena 連接器運作所需的 TableType 屬性。一般來說，這些表格的中繼資料不會遷移到 AWS Glue 資料目錄。如需詳細資訊，請參閱《 開發人員指南》中的Step-by-Step升級至 AWS Glue Data Catalog。 AWS Glue
如果您目前不想遷移至 AWS Glue Data Catalog，您有兩個選項。您可以透過 AWS Glue 管理主控台重新建立每個 AWS Glue 資料表。或者，您可以使用下列程序中列出的 AWS CLI 指令碼來識別和更新缺少TableType屬性的資料表。
如果您偏好使用 CLI 來執行此操作，請使用下列程序來協助您設計您的指令碼。
若要使用 CLI 設計指令碼
-
使用 CLI 來了解哪些 AWS Glue 資料表沒有
TableType屬性。aws glue get-tables --database-name <your_datebase_name>;例如，您可以在 CLI 中執行下列命令。
aws glue get-table --database-name "test_database" --name "table_missing_table_type"以下是輸出的範例。您可以看到表格
"table_missing_table_type"沒有宣告TableType屬性。{ "TableList": [ { "Retention": 0, "UpdateTime": 1522368588.0, "PartitionKeys": [ { "Name": "year", "Type": "string" }, { "Name": "month", "Type": "string" }, { "Name": "day", "Type": "string" } ], "LastAccessTime": 1513804142.0, "Owner": "owner", "Name": "table_missing_table_type", "Parameters": { "delimiter": ",", "compressionType": "none", "skip.header.line.count": "1", "sizeKey": "75", "averageRecordSize": "7", "classification": "csv", "objectCount": "1", "typeOfData": "file", "CrawlerSchemaDeserializerVersion": "1.0", "CrawlerSchemaSerializerVersion": "1.0", "UPDATED_BY_CRAWLER": "crawl_date_table", "recordCount": "9", "columnsOrdered": "true" }, "StorageDescriptor": { "OutputFormat": "org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat", "SortColumns": [], "StoredAsSubDirectories": false, "Columns": [ { "Name": "col1", "Type": "string" }, { "Name": "col2", "Type": "bigint" } ], "Location": "s3://myAthenatest/test_dataset/", "NumberOfBuckets": -1, "Parameters": { "delimiter": ",", "compressionType": "none", "skip.header.line.count": "1", "columnsOrdered": "true", "sizeKey": "75", "averageRecordSize": "7", "classification": "csv", "objectCount": "1", "typeOfData": "file", "CrawlerSchemaDeserializerVersion": "1.0", "CrawlerSchemaSerializerVersion": "1.0", "UPDATED_BY_CRAWLER": "crawl_date_table", "recordCount": "9" }, "Compressed": false, "BucketColumns": [], "InputFormat": "org.apache.hadoop.mapred.TextInputFormat", "SerdeInfo": { "Parameters": { "field.delim": "," }, "SerializationLibrary": "org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe" } } } ] } -
在您的編輯器中編輯表格定義，將
"TableType": "EXTERNAL_TABLE"新增到表格定義，如以下範例所示。{ "Table": { "Retention": 0,"TableType": "EXTERNAL_TABLE","PartitionKeys": [ { "Name": "year", "Type": "string" }, { "Name": "month", "Type": "string" }, { "Name": "day", "Type": "string" } ], "UpdateTime": 1522368588.0, "Name": "table_missing_table_type", "StorageDescriptor": { "BucketColumns": [], "SortColumns": [], "StoredAsSubDirectories": false, "OutputFormat": "org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat", "SerdeInfo": { "SerializationLibrary": "org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe", "Parameters": { "field.delim": "," } }, "Parameters": { "classification": "csv", "CrawlerSchemaSerializerVersion": "1.0", "UPDATED_BY_CRAWLER": "crawl_date_table", "columnsOrdered": "true", "averageRecordSize": "7", "objectCount": "1", "sizeKey": "75", "delimiter": ",", "compressionType": "none", "recordCount": "9", "CrawlerSchemaDeserializerVersion": "1.0", "typeOfData": "file", "skip.header.line.count": "1" }, "Columns": [ { "Name": "col1", "Type": "string" }, { "Name": "col2", "Type": "bigint" } ], "Compressed": false, "InputFormat": "org.apache.hadoop.mapred.TextInputFormat", "NumberOfBuckets": -1, "Location": "s3://myAthenatest/test_date_part/" }, "Owner": "owner", "Parameters": { "classification": "csv", "CrawlerSchemaSerializerVersion": "1.0", "UPDATED_BY_CRAWLER": "crawl_date_table", "columnsOrdered": "true", "averageRecordSize": "7", "objectCount": "1", "sizeKey": "75", "delimiter": ",", "compressionType": "none", "recordCount": "9", "CrawlerSchemaDeserializerVersion": "1.0", "typeOfData": "file", "skip.header.line.count": "1" }, "LastAccessTime": 1513804142.0 } } -
您可以調整以下指令碼更新表格輸入，以便包含
TableType屬性。aws glue update-table --database-name <your_datebase_name> --table-input <updated_table_input>下列顯示一個範例。
aws glue update-table --database-name test_database --table-input ' { "Retention": 0, "TableType": "EXTERNAL_TABLE", "PartitionKeys": [ { "Name": "year", "Type": "string" }, { "Name": "month", "Type": "string" }, { "Name": "day", "Type": "string" } ], "Name": "table_missing_table_type", "StorageDescriptor": { "BucketColumns": [], "SortColumns": [], "StoredAsSubDirectories": false, "OutputFormat": "org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat", "SerdeInfo": { "SerializationLibrary": "org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe", "Parameters": { "field.delim": "," } }, "Parameters": { "classification": "csv", "CrawlerSchemaSerializerVersion": "1.0", "UPDATED_BY_CRAWLER": "crawl_date_table", "columnsOrdered": "true", "averageRecordSize": "7", "objectCount": "1", "sizeKey": "75", "delimiter": ",", "compressionType": "none", "recordCount": "9", "CrawlerSchemaDeserializerVersion": "1.0", "typeOfData": "file", "skip.header.line.count": "1" }, "Columns": [ { "Name": "col1", "Type": "string" }, { "Name": "col2", "Type": "bigint" } ], "Compressed": false, "InputFormat": "org.apache.hadoop.mapred.TextInputFormat", "NumberOfBuckets": -1, "Location": "s3://myAthenatest/test_date_part/" }, "Owner": "owner", "Parameters": { "classification": "csv", "CrawlerSchemaSerializerVersion": "1.0", "UPDATED_BY_CRAWLER": "crawl_date_table", "columnsOrdered": "true", "averageRecordSize": "7", "objectCount": "1", "sizeKey": "75", "delimiter": ",", "compressionType": "none", "recordCount": "9", "CrawlerSchemaDeserializerVersion": "1.0", "typeOfData": "file", "skip.header.line.count": "1" }, "LastAccessTime": 1513804142.0 }'
