My Dataset< Row > (java spark) input is :
| Heros | Powers | Rank |
|---|---|---|
| Superman | Invisible | 1 |
| Batman | Strength | 2 |
| SpiderMan | Strong | 3 |
By knowing the name of my heros, i would like to retrieve the rank. For exemple for Superman, i would like to have the return 1, not all the line but just the value. I don't know how to do by using a spark dataset. Thank for your help !
