Max of multiple columns of a row in spark

[kushagra deep]

Hi Guys,

I have a problem where I have a df as below:

===+
Marks1 | Marks2| Marks3 |
  10. 30.  40. |

I want to add a new column in the df with name Max with the max of the
values of the three columns.

The resultant df should be :

===+
Marks1| Marks2| Marks3 | Max |
 10. 30. 40.   40

Thanks In Advance

Reg,
