In Yandex MPP Analytics for PostgreSQL, you can use HDFS as part of Yandex Data Processing or other third-party HDFS services as an external data source with the HDFS connection type.

Create an external data source

Management console

REST API

gRPC API

Open the folder dashboard.
Navigate to the Yandex MPP Analytics for PostgreSQL service.
Open the page of the Greenplum® cluster in question.
In the left-hand panel, select PXF.
Click Create data source.
Select the HDFS connection type.
Enter a source name.
Configure at least one optional setting.
Click Create.

Get an IAM token for API authentication and put it in an environment variable:
```
export IAM_TOKEN="<IAM_token>"
```

Use the PXFDatasource.Create method and send the following request, e.g., via cURL:

curl \
    --request POST \
    --header "Authorization: Bearer $IAM_TOKEN" \
    --header "Content-Type: application/json" \
    --url 'https://mdb.api.cloud.yandex.net/managed-greenplum/v1/clusters/<cluster_ID>/pxf_datasources' \
    --data '{
              "datasource": {
                "name": "<external_data_source_name>",
                "hdfs": {
                  "core": {
                    "defaultFs": "<storage_type>"
                  },
                  ...
                }
              }
            }'

Where:

name: External data source name.
hdfs: External data source settings. Configure at least one optional setting.

You can get the cluster ID with the list of clusters in the folder.

View the server response to make sure your request was successful.

Get an IAM token for API authentication and put it in an environment variable:
```
export IAM_TOKEN="<IAM_token>"
```
Clone the cloudapi repository:
```
cd ~/ && git clone --depth=1 https://github.com/yandex-cloud/cloudapi
```
Below, we assume that the repository contents reside in the ~/cloudapi/ directory.

Use the PXFDatasourceService.Create call and send the following request, e.g., via gRPCurl:

grpcurl \
    -format json \
    -import-path ~/cloudapi/ \
    -import-path ~/cloudapi/third_party/googleapis/ \
    -proto ~/cloudapi/yandex/cloud/mdb/greenplum/v1/pxf_service.proto \
    -rpc-header "Authorization: Bearer $IAM_TOKEN" \
    -d '{
          "cluster_id": "<cluster_ID>"
          "datasource": {
            "name": "<external_data_source_name>",
            "hdfs": {
              "core": {
                "default_fs": "<storage_type>"
              },
              ...
            }
          }
        }' \
    mdb.api.cloud.yandex.net:443 \
    yandex.cloud.mdb.greenplum.v1.PXFDatasourceService.Create

Where:

name: External data source name.
hdfs: External data source settings. Configure at least one optional setting.

You can get the cluster ID with the list of clusters in the folder.

View the server response to make sure your request was successful.
