how to change data type for columns of dataframe

[ca...@free.fr]

Hi

I got a dataframe object from other application, it means this obj is 
not generated by me.
How can I change the data types for some columns in this dataframe?

For example, change the column type from Int to Float.

Thanks.

Please use cast. Also I would strongly recommend to go through spark doco,
its pretty good.
