Starting and Logging in to Transformer

Use the command prompt to start Transformer from the $TRANSFORMER_DIST directory, the location where you extracted the tarball and the base Transformer runtime directory.

When you start Transformer, Transformer runs as the user account logged into the command prompt. You can alternatively impersonate another user account when you run the command.

  1. Use one of the following commands from the $TRANSFORMER_DIST directory to start Transformer.
    To start Transformer with Kerberos enabled while allowing proxy users, use one of the following commands:
    • To run Transformer as the system user account logged into the command prompt, use:
      k5start -f <path to keytab file> -L <Kerberos principal> -- bin/streamsets transformer 
    • To run Transformer in the background as the system user account logged into the command prompt, use:
      nohup k5start -f <path to keytab file> -L <Kerberos principal> --  bin/streamsets transformer &
    • To run Transformer as another system user account, use:
      sudo -u <user> k5start -f <path to keytab file> -L <Kerberos principal> -- bin/streamsets transformer
    To start Transformer in all other cases, use one of the following commands:
    • To run Transformer as the system user account logged into the command prompt, use:
      bin/streamsets transformer 
    • To run Transformer in the background as the system user account logged into the command prompt, use:
      nohup bin/streamsets transformer &
    • To run Transformer as another system user account, use:
      sudo -u <user> bin/streamsets transformer
  2. To access the Transformer UI, enter the following URL in the address bar of your browser:
