Corrected entry: When Luke sees the ethereal Obi-Wan, Obi-Wan tells Luke to go see Yoda in the Dagobah system, to be trained by the Jedi who trained him. But we learn in Phantom Menace that Obi-Wan wasn't trained by Yoda, he was trained by Qui-Gon Jinn.

Correction: Obi-wan was trained directly by Yoda the entire time he was a youngling. It wasn't until he was old enough that he was allowed to be a Padawan of another Jedi. And even then, Yoda oversaw both he and Qui-gon.
