>             Project: Apache Airflow
>          Issue Type: Bug
>          Components: core
>    Affects Versions: Airflow 1.7.1.2
>         Environment: ubuntu 14.04 (python 2.7), new virtualenv, pip install airflow
>            Reporter: Brian Candler
>            Assignee: Chris Riccomini

>              Labels: newbie
>             Fix For: Airflow 1.8

> When running the quickstart instructions at http://pythonhosted.org/airflow/start.html inside a clean virtualenv:
> ERROR [airflow.models.DagBag] Failed to import:
> /home/brian/airflow/venv/local/lib/python2.7/site-packages/airflow/example_dags/example_twitter_dag.py
> Traceback (most recent call last):
>   File
> "/home/brian/airflow/venv/local/lib/python2.7/site-packages/airflow/models.py",
> line 247, in process_file
>     m = imp.load_source(mod_name, filepath)
>   File
> "/home/brian/airflow/venv/local/lib/python2.7/site-packages/airflow/example_dags/example_twitter_dag.py",
> line 26, in <module>
>     from airflow.operators import BashOperator, HiveOperator,
> PythonOperator
> ImportError: cannot import name HiveOperator
> Unfortunately that message doesn't help diagnose the problem, which is being hidden by auto-import magic.
> It requires manually probing imports from the true source modules:
> >>> from airflow.operators.hive_operator import HiveOperator
> ...
> ImportError: cannot import name HiveCliHook
> >>> from airflow.hooks.hive_hooks import HiveCliHook
> ...
> ImportError: No module named unicodecsv
> Aha. "pip install unicodecsv" fixes the error.
> So I'd suggest two issues:
> 1. Add a packaging dependency on unicodecsv to fix this particular problem
> 2. Fix the auto-import magic so that it doesn't suppress these errors
