> Getting an exception when trying to view task logs in the web ui:
> Traceback (most recent call last):
>   File "/Users/dy001ra/git/incubator-airflow/airflow/www/views.py", line 725, in log
>     logs = handler.read(ti)
>   File "/Users/dy001ra/git/incubator-airflow/airflow/utils/log/file_task_handler.py",
line 148, in read
>     logs[i] += self._read(task_instance, try_number)
>   File "/Users/dy001ra/git/incubator-airflow/airflow/utils/log/file_task_handler.py",
line 91, in _read
>     log_relative_path = self._render_filename(ti, try_number + 1)
>   File "/Users/dy001ra/git/incubator-airflow/airflow/utils/log/file_task_handler.py",
line 71, in _render_filename
>     jinja_context = ti.get_template_context()
>   File "/Users/dy001ra/git/incubator-airflow/airflow/utils/db.py", line 48, in wrapper
>     result = func(*args, **kwargs)
>   File "/Users/dy001ra/git/incubator-airflow/airflow/models.py", line 1551, in get_template_context
>     task = self.task
> AttributeError: 'TaskInstance' object has no attribute 'task'
> From looking through the code it appears that the logging file_task_handler expects the
TaskInstance to contain a reference to its task object.
