### Method Details

`cancel(name=None, body, x__xgafv=None)`

    Cancels a running job.

    Args:
      name: string, Required. The name of the job to cancel.

    Authorization: requires `Editor` role on the parent project. (required)
      body: object, The request body. (required)
        The object takes the form of:

    { # Request message for the CancelJob method.
      }

      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

        { # A generic empty message that you can re-use to avoid defining duplicated
          # empty messages in your APIs. A typical example is to use it as the request
          # or the response type of an API method. For instance:
          #
          #     service Foo {
          #       rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty);
