{code}

Investigation shows that file ambari-server/src/main/resources/common-services/HIVE/0.12.0.2.0/package/scripts/mysql.py
is not imported because it conflicts with standard python package "mysql" that is installed
on my machine.

{code}
>>> import mysql
>>> print mysql
<module 'mysql' from '/usr/lib/pymodules/python2.7/mysql/__init__.pyc'>
{code}

*This code may also fail on some production environments.*
The solution is to rename file at our project
