> Currently float is supported by internally storing the data as double and
> changing the data type to Double. This poses some problems while using
> SparkCarbonFileFormat for reading the float type data.
> Internally as the data type is changed from Float to Double therefore the
> data is retrieved as a Double page instead of float.
> If the user tried to create a table using file format by specifying the
> datatype as float for any column then the query will fail. User is
> *restricted to use double to retrieve the data.*
