Question

我正在尝试使用c＃athena驱动程序执行athena查询。

Amazon.Athena.Model.ResultConfiguration resultConfig = new Amazon.Athena.Model.ResultConfiguration();
resultConfig.OutputLocation = "https://s3.us-east-2.amazonaws.com/testbucket/one/2018-02-06/";
//other inputs i have tried
//"s3://testbucket/one/2018-02-06/"
//testbucket

//Populate the request object
                Amazon.Athena.Model.StartQueryExecutionRequest queryExec = new Amazon.Athena.Model.StartQueryExecutionRequest();
                queryExec.QueryString = query.QueryString;
                queryExec.QueryExecutionContext = queryExecutionContext;
                queryExec.ResultConfiguration = resultConfig;

StartQueryExecutionResponse athenaResponse = athenaClient.StartQueryExecution(queryExec);//throws exception

不同案例的例外情况：

outputLocation不是有效的S3路径。提供https://s3.us-east-2.amazonaws.com/testbucket/one/2018-02-06/



无法验证/创建输出存储桶testbucket。提供s3：// testbucket / one / 2018-02-06 /



无法验证/创建输出存储桶testbucket。提供了testbucket

有人可以用正确的s3格式帮助我吗？

提前致谢。

Answer 1

输出位置需要采用以下格式：

s3://{bucketname}/{path}

在您的情况下，这将导致以下位置：

resultConfig.OutputLocation = "s3://testbucket/one/2018-02-06/";

Answer 2

Amazon.Athena.AmazonAthenaClient _client = new Amazon.Athena.AmazonAthenaClient(AwsAccessKeyId, AwsSecretAccessKey, EndPoint);
                Amazon.Athena.Model.ResultConfiguration resultConfig = new Amazon.Athena.Model.ResultConfiguration();
                resultConfig.OutputLocation = "s3://"+BucketName+"/key1/";                
                string query = "SELECT * FROM copalanadev.logs";
                //Populate the request object
                Amazon.Athena.Model.StartQueryExecutionRequest queryExec = new Amazon.Athena.Model.StartQueryExecutionRequest();
                queryExec.QueryString = query;
                //queryExec.QueryExecutionContext = queryExecutionContext;
                queryExec.ResultConfiguration = resultConfig;

            StartQueryExecutionResponse athenaResponse = _client.StartQueryExecution(queryExec);//throws exception

outputLocation不是有效的S3路径。雅典娜例外
