Review request for ranger, Alok Lal, Don Bosco Durai, Gautam Borad, Abhay 
Kulkarni, Madhan Neethiraj, Ramesh Mani, and Selvamohan Neethiraj.


Bugs: RANGER-896
    https://issues.apache.org/jira/browse/RANGER-896


Repository: ranger


Description
-------

**Problem Statement :** Currently Ranger works with MySQL Database, Since 
MariaDB is similar to MySQL; Ranger should work with MariaDB also.

**Proposed Solution :**

Proposed attached patch is optional and contains removal of storage engine 
type(InnoDB) from all tables where schema has 'ENGINE=InnoDB' clause.

No mandatory changes are required to support MariaDB. User will have to provide 
:
- DB_FLAVOR=MYSQL,
- MariaDB hostname/ip details and 
- DB credentials in install.properties file 

The rest of the flow will remain similar to MYSQL.
