snazzyfox opened a new issue #8933:
URL: https://github.com/apache/airflow/issues/8933
**Apache Airflow version**: 1.10.10
(appears to also affect master)
**What happened**:
When airflow is installed with Hive support using `apache-airflow[hive]`,
using HiveServer2Hook to run a query throws the following exception:
```
...
File "/usr/local/lib/python3.7/site-packages/airflow/hooks/hive_hooks.py",
line 828, in get_conn
database=schema or db.schema or 'default')
File "/usr/local/lib/python3.7/site-packages/pyhive/hive.py", line 94, in
connect
return Connection(*args, **kwargs)
File "/usr/local/lib/python3.7/site-packages/pyhive/hive.py", line 152, in
__init__
import sasl
ModuleNotFoundError: No module named 'sasl'
```
**What you expected to happen**:
The error should not appear.
**How to reproduce it**:
Any minimal dag that uses HiveServer2Hook generates the error. Connection to
a working Hive cluster is not required since the required dependencies are not
installed
**Probable Reason**:
For `pyhive` to work with Hive, it should be installed as `pyhive[hive]`.
The hive extra brings in the `sasl` package.
This is not caught testing since tests run with all the dependencies, and
the packages required by
[`pyhive[hive]`](https://github.com/dropbox/PyHive/blob/master/setup.py#L47)
happen to be also used for
[`kerberos`](https://github.com/apache/airflow/blob/master/setup.py#L313).
I know this will be a much bigger conversation, but maybe it's worth it to
consider testing operators _only_ with the dependencies they're supposed to
rely on?
