Cloud Hadoop is a NAVER Cloud Platform service that allows users to freely use open source-based frameworks such as Apache Hadoop, HBase, Spark, Hive, and Presto to process big data easily and quickly. Cloud Hadoop provides APIs for creating Hadoop clusters, adding worker nodes, and querying resources in the RESTful form.

Common Cloud Hadoop settings

The following describes commonly used request and response formats in Cloud Hadoop APIs.

Request

The following describes the common request format.

API URL

The request API URL is as follows:

  • Request is considered invalid if the timestamp differs from the current time by more than 5 minutes.
x-ncp-apigw-api-key Required API key issued by the API Gateway service of NAVER Cloud Platform
x-ncp-iam-access-key Required Access key issued on NAVER Cloud Platform
x-ncp-apigw-signature-v2 Required Base64-encoded signature that encrypts the request information with a secret key that maps to the access key issued on NAVER Cloud Platform, using the HMAC encryption algorithm (HmacSHA256)

Response

The following describes the common response format.

HTTP status code Code Message Description
400 900 Required field is not specified. location: [Parameter name] Missing required parameter
  • Add required parameter and try again.
500 908 workerNodeCount is invalid. workerNodeCount should be in [2, 12] Number of worker nodes exceeds the range of increase/decrease.
  • Edit with 10 or fewer change values and try again.
500 929 Please try your call again later.\nTemporarily out of service.\nIf error continue, Please contact our customer service center. Temporary error
  • Try again later or contact Support of the NAVER Cloud Platform portal if the problem persists.

  • Try again after editing the cluster instance number.
Note

For response status codes common to NAVER Cloud Platform, see Ncloud API response status codes.

Response example

For response examples when a call is successful, see each API specification. The following is a sample response upon a failed call.

  • JSON
    {

    }
}
  • XML

    <returnCode>string</returnCode>
    <returnMessage>string</returnMessage>
</error>
