Well, not exactly the same but close:
apishi = burners (people who burn sth) Ndau
vapisi = burners (people who burn sth) Shona
What is more interesting is that Swahili chose to use a different word from the verb infinitive "to cook" , which is "kupika" All the Bantu languages I know derive the noun "cook" from the infinitive verb "to cook" .
A few examples:
Infinitive: kubika = to cook , noun: mubiki/abiki = cook/cooks --- Ndau
Infinitive: ukupheka = to cook , noun: umpheki/abapheki = cook/cooks --- Ndebele
Infinitive: kuapeha = to cook , noun: muapehi/baapehi = cook/cooks --- Lozi
