Register Transformer

For a Transformer tarball installation, you can register Transformer with Control Hub using the command line interface.

When you register Transformer from the command line interface, Transformer generates the authentication token and modifies the configuration files for you. Transformer must be running before you can use the command line interface.

Start Transformer, and then use the system enableDPM command to register Transformer.

Use the command from the $TRANSFORMER_DIST directory as follows:

bin/streamsets cli \
(-U <sdcURL> | --url <sdcURL>) \
[(-D <dpmURL> | --dpmURL <dpmURL>)] \
[(-a <sdcAuthType> | --auth-type <sdcAuthType>)] \
[(-u <sdcUser> | --user <sdcUser>)] \
[(-p <sdcPassword> | --password <sdcPassword>)] \
system enableDPM \
(--dpmUrl <dpmBaseURL>) \
(--dpmUser <dpmUserID>) \
(--dpmPassword <dpmUserPassword>) \
[(--labels <labels>)]

When using the system enableDPM command, the following basic options are required:

The following table describes the enableDPM options:

<ID>@<organization ID>

bin/streamsets cli -U http://localhost:19630 -D https://cloud.streamsets.com system enableDPM --dpmUrl https://cloud.streamsets.com --dpmUser alison@MyOrg --dpmPassword MyPassword --labels Finance,Accounting,Development

Restart Transformer to apply the changes.

If you register Transformer when it is installed on a cloud computing platform such as Amazon Elastic Compute Cloud (EC2), configure Transformer to use a publicly accessible URL.

When you register Transformer with Control Hub, Transformer sends its URL to Control Hub in the format http://<hostname>:<http.port>, where <hostname> is the value defined in the http.bindHost property in the Transformer configuration file, $TRANSFORMER_CONF/transformer.properties. If the host name is not defined in http.bindHost, Transformer runs the following command to determine the host name: hostname -f

For most cloud computing platforms, the hostname -f command returns the private IP address of the machine on the cloud platform. Control Hub includes the private IP address in the Transformer URL displayed in Control Hub. However, when you click the Transformer URL, you cannot access Transformer because you must use a public IP address to access a cloud machine.

To access Transformer installed on a cloud computing platform from Control Hub, uncomment the transformer.base.http.url property in the Transformer configuration file, $TRANSFORMER_CONF/transformer.properties, and then configure it to use the publicly accessible URL to that Transformer.

After modifying the configuration file, restart Transformer for the changes to take effect.

You can configure each registered Transformer to use an authenticated HTTP or HTTPS proxy server for outbound requests made to Control Hub. Define the proxy properties in the TRANSFORMER_JAVA_OPTS environment variable.

Modify environment variables using the method required by your installation type.

Add the following Java options to the TRANSFORMER_JAVA_OPTS environment variable:

• https.proxyUser
• https.proxyPassword
• https.proxyHost
• https.proxyPort

If the proxy server uses HTTP instead of HTTPS, use http.<property name> for each property.

For example, to configure a registered Transformer to use an HTTPS proxy server on host 138.0.0.1 and port 3138, define TRANSFORMER_JAVA_OPTS as follows:

export TRANSFORMER_JAVA_OPTS="${TRANSFORMER_JAVA_OPTS} -Xmx1024m -Xms1024m -Dhttps.proxyUser=MyName -Dhttps.proxyPassword=MyPsswrd -Dhttps.proxyHost=138.0.0.1 -Dhttps.proxyPort=3138 -server"
