Description

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.
