我正在从某些来源获取数据，现在想将其提供给Kinesis Firehose交付流。我在amazonKinesisFirehoseClient.putRecord（putRecordRequest）处收到“状态代码：400；错误代码：UnknownOperationException”；
我的密码
while (data != null) {
PutRecordRequest putRecordRequest = new PutRecordRequest();
putRecordRequest.setDeliveryStreamName("xxxxxxxxxx");
String line = data + "\n";
System.out.println("Data ---------> " + line);
com.amazonaws.services.kinesisfirehose.model.Record recordData = createRecord(line);
putRecordRequest.setRecord(recordData);
System.out.println("Inside single row transfer 2222222222 --------------------");
// Put record into the DeliveryStream
amazonKinesisFirehoseClient.putRecord(putRecordRequest);
System.out.println("Endddddd single row transfer --------------------");
}
输出量
Inside single row transfer 111111111 --------------------
Data --------->{"name":"xxxxxxxx","id":xxx,"address":xxxxxxxx,"phoneNumber":"xxxxxxxxxx","age":xx}
Inside single row transfer 2222222222 --------------------

我非常确定我与Kinesis Firehose连接的所有凭据均正确。我在Kinesis Firehose中很好地映射了S3和RedShift）
提前致谢 ：）
最佳答案
在将端点配置为使用https://kinesis.us-east-1.amazonaws.com而不是https://firehose.us-east-1.amazonaws.com时，我已经看到类似的错误。尝试设置该值以查看是否有帮助。
另外，如果您使用的是支持该版本的SDK，则可以使用AmazonKinesisFirehoseClientBuilder并设置区域字符串以避免使用错误的终端节点：
AmazonKinesisFirehose firehoseClient = AmazonKinesisFirehoseClientBuilder
.standard()
.withRegion("us-west-2")
.build()
