> When a DP job is cancelled, {{gcp_dataproc_hook.py}} does not treat the {{CENCELLED}} state in a consistent and non-intuitive manner:
> # The API internal to {{gcp_dataproc_hook.py}} returns {{False}} from {{_DataProcJob.wait_for_done()}}, resulting in {{raise_error()}} being called for cancelled jobs, yet {{raise_error()}} only raises {{Exception}} if the job state is {{ERROR}}.
> # The end result from the perspective of the {{dataproc_operator.py}} for a cancelled job is that the job succeeded, which results in the success callback being called.  This seems strange to me, as a "cancelled" job is rarely considered successful, in my experience.
> Simply changing {{raise_error()}} from:
> {code:python}
>         if 'ERROR' == self.job['status']['state']:
> {code}
> to
> {code:python}
>         if self.job['status']['state'] in ('ERROR', 'CANCELLED'):
> {code}
> would fix both of these...
