Set environment variables in the <code>EXECUTE</code> clause. The following external web table, for example, runs a command on the HAWQ master host:</p>

+<p>The <code>gpfdist</code> configuration file uses the YAML 1.1 document format and implements a schema for defining the transformation parameters. The configuration file must be a valid YAML document.</p>
 
 <p>The <code>gpfdist</code> program processes the document in order and uses indentation (spaces) to determine the document hierarchy and relationships of the sections to one another. The use of white space is significant. Do not use white space for formatting and do not use tabs.</p>
