Definitely not; a handful of non-relational databases use MapReduce, but definitely not all of them or even a majority of them. Others provide a simple key-value interface, graph query languages, custom languages, or custom API.

"post-relational" aka Pick all use roughly the same query language, called originally ENGLISH or in its other variants RETRIEVE, PERFORM and probably more. It is very english-like hence the name, but bear in mind it is a *query* language only. It was meant to be an update language too, like SQL, but that fell by the wayside as being "too complicated". And it is complicated. Horribly.

(I understand SQL was originally SEQL, "Simple English Query Language", but they changed it when it became complicated and un-english-like :-)
