You can create connections to SFTP servers to upload your datasets to the 



SSH Keys

If preferred, you can use SSH keys to for authentication to the SFTP server.

NOTE: SSH keys must be private RSA keys. If you have OpenSSH keys, you can use the ssh-keygen utility to convert them to private RSA keys.


By default, this connection type is automatically enabled.

NOTE: You must provide the protocol identifier and storage locations for the SMTP server. See below.

Configure file storage protocols and locations

The  must be provided the list of protocols and locations for accessing SFTP. 


  1. Locate the following parameters and set their values according to the table below:

    "fileStorage.whitelist": ["sftp"],
    "fileStorage.defaultBaseUris": ["sftp:///"],


    A comma-separated list of protocols that are permitted to access SFTP.

    NOTE: The protocol identifier "sftp" must be included in this list.


    For each supported protocol, this param must contain a top-level path to the location where files can be stored. These files include uploads, samples, and temporary storage used during job execution.

    NOTE: A separate base URI is required for each supported protocol. You may only have one base URI for each protocol.

    NOTE: For SFTP, three slashes at the end are required, as the third one is the path value.

  2. Save your changes and restart the platform.

Java VFS service

Use of SFTP connections requires the Java VFS service in the .

NOTE: This service is enabled by default.

For more information on configuring this service, see Configure Java VFS Service.

Create Connection
