This is fantastic, [~sergey.soldatov]! Who would be the best person to review this? Maybe [~enis] or [~elserj]? Also, would you mind filing a separate JIRA to update the docs?

> If column mapping is used during table creation, the hive table becomes unusable and throws UnknownColumn exception.
> There are several issues in the current implementation:
> 1. During table creation mapping doesn't applies to primary keys
> 2. During select query building no mapping happen
> 3. PhoenixRow should have backward mapping from phoenix column names to hive names.
