如果您在使用 Athena 和 A QuickSight mazon 中的 AWS Glue 表格时遇到错误，可能是因为您缺少了一些元数据。请按照以下步骤查看您的表格是否不具有 Amazon 让 Athena 连接器正常工作 QuickSight 所需的TableType属性。通常，这些表的元数据未迁移到 AWS Glue 数据目录。有关更多信息，请参阅《 AWS Glue 开发人员指南》 Step-by-Step中的升级到 AWS Glue 数据目录。
如果您此时不想迁移到 AWS Glue 数据目录，则有两种选择。您可以通过 AWS Glue 管理控制台重新创建每 AWS Glue 张表。或者，您可以使用以下过程中列出的 AWS CLI 脚本来识别和更新缺少TableType属性的表。
如果您更希望使用 CLI 执行此操作，请使用以下过程以帮助您设计脚本。
使用 CLI 设计脚本
-
使用 CLI 了解哪些 AWS Glue 表没有
TableType属性。aws glue get-tables --database-name <your_datebase_name>;例如，可以在 CLI 中运行以下命令。
aws glue get-table --database-name "test_database" --name "table_missing_table_type"下面是输出内容的示例。可以看到，表
"table_missing_table_type"未声明TableType属性。{ "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" } } } ] } -
在编辑器中编辑表定义，将
"TableType": "EXTERNAL_TABLE"添加到表定义，如下例所示。{ "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 } } -
您可以改写以下脚本以更新表输入，使其包含
TableType属性。aws glue update-table --database-name <your_datebase_name> --table-input <updated_table_input>下面是一个示例。
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 }'
