Radoop Proxy

Radoop Proxy lets you tunnel all Radoop connections through a single machine residing on the edge of your secure Hadoop cluster. Its purpose is to significantly reduce the number of ports that need to be opened on the firewall protecting the Hadoop cluster, making the networking configuration much easier.

Radoop Proxy architecture

Radoop Proxy is a component that is conveniently shipped in multiple ways:

• bundled with RapidMiner Server
• as aseparate Docker container(which can be used as a standalone instance or as part of a RapidMiner Server deployment)

它可以接受来自RapidMiner工作室的连接nd forward these connections towards Hadoop, forming a single access point to the cluster. It is typically installed on one of the secured cluster machines (this can be an existing Hadoop node, or a dedicated machine / edge node), so it resides on the same local network as the cluster nodes. To allow outside access to the secured cluster, only ahandful of portsneed to be opened on the firewall, making thedefault networking setupobsolete.

To ensure security, RapidMiner Studio users must be authenticated when using the Radoop Proxy. Authentication is done by a RapidMiner Server that is connected to the Radoop Proxy, or with a standalone username/password combination (depending on Radoop Proxy configuration).

The connection between RapidMiner Studio users and Radoop Proxy can be easilysecured with SSLif the certificates for the machine hosting the proxy is available. Since bothRapidMiner服务器用户and Hadoop users can be managed in a central LDAP server, this enables a centralized and convenient user management as well.

Setting up a Radoop Proxy Connection

1. Make sure thatNetworking requirements(hostname resolution, firewall rules) are in place and Radoop Proxy isinstalledon a node located inside the network of the Hadoop cluster.

2. Create a newRadoop Proxy Connectionfrom RapidMiner Studiobelonging to any local or remote repositories of your choice. The fields on the Setup tab are explained below:

   

   Field	Description
   Radoop Proxy Server host	IP address or hostname of the Radoop Proxy server
   Radoop Proxy Server port	Radoop Proxy Server port. Default is 1081
   Use Enterprise SSO	Use the Enterprise SSO token from the parent Repository. Only displayed with Radoop Proxy Connections that are in Repository Panel. Should only be used with a Radoop Proxy Server configured with SAML/Keycloak authentication seeCustom Radoop Proxy Installationfor details.RapidMiner Server userandRapidMiner Server passwordare disabled when this feature is used.
   RapidMiner Server user	Username for authenticating. This is disabled whenUse Enterprise SSOis checked.
   RapidMiner Server password	Password to use for the connection. This is disabled whenUse Enterprise SSOis checked.
   Use secure (SSL) connection	Use SSL for the proxy connection. SeeRadoop Proxy securityfor details. If your certificate is NOT well-known then you need to fill inKeystore fileandKeystore password.
   Keystore file (SSL)	Keystore file that contains the SSL cert to use, if cert is well known, you can leave this empty. This is disabled whenUse secure (SSL) connectionis unchecked.
   Keystore password (SSL)	password to use to unlock the keystore, if keystore has no password, you can leave this empty. This is disabled whenUse secure (SSL) connectionis unchecked.

3. In the连接menu, selectManage Radoop Connections, edit your connection by clickingConfigure, and on theRadoop Proxytab checkUse Radoop Proxy:

   

4. Select the location of your proxy definition from the first dropdown selector in theRadoop Proxy Connectionsection. ChooseLocal Repositoryfor connection set up in Studio or the name of the Server repository in case of remote connections.

5. Select the connection from the second dropdown selector in theRadoop Proxy Connectionsection. In case of server locations you may need to click on theRefreshbutton to sync the connections from the Server to Studio. You also have the option to click onEditbutton to edit an existing or to create a new Radoop Proxy connection right from this screen.
