> Project: CarbonData
> Issue Type: New Feature
> Components: sql

> Reporter: Yahui Liu
> Priority: Major
> Time Spent: 40m

> Currently when create carbon hive table, if data type is float, will convert
> to double type. This means all float data will be stored as double.
> In CTAS secnario, if source table column is float type, the data in newly
> created carbon table will be incorrect.
> Reproduce steps:
> CREATE TABLE p1(f float) stored as parquet;
> insert into table p1 select 12.36;
> create table carbon1 stored as carbondata as select * from p1;
> select * from carbon1;
> Result:
> 5.410467587E-315
> Carbon should support store float datatype directly.
