> PROBLEM:
> As per the Hive Language DDL: 
> https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL
> In Hive 0.12 and earlier, only alphanumeric and underscore characters are allowed in table and column names.
> In Hive 0.13 and later, column names can contain any Unicode character (see HIVE-6013). Any column name that is specified within backticks (`) is treated literally.
> However column names
> {code}
> ` left` resulted in `left`
> ` middle ` resulted in `middle`
> `right ` resulted in `right`
> `middle space` resulted in `middle space`
> ` middle space ` resulted in `middle space`
> {code}
