 * @throws {@link DuplicateRequest} (client fault)
 *  <p>The operation is already in progress.</p>
 *
 * @throws {@link InvalidInput} (client fault)
 *  <p>One or more specified values aren't valid. For example, a required value might be missing, a
 *    numeric value might be outside the allowed range, or a string value might exceed length
 *    constraints.</p>
 *
 * @throws {@link NamespaceNotFound} (client fault)
 *  <p>No namespace exists with the specified ID.</p>
 *
 * @throws {@link ResourceInUse} (client fault)

 * @example To update a HTTP namespace
 * ```javascript
 * // The following example updates the description of a HTTP namespace.
 * const input = {

 * @example Update HTTP namespace using namespace ARN for shared namespace
