Urs Holzle, the senior vice president of technical infrastructure and Google Fellow at Google and Google's eighth employee, announced Google is not using MapReduce anymore. But don't you worry, this has zero impact on Google Search and your rankings implies Google's John Mueller.
Here is the announcement:
@JeffDean @GCPcloud R.I.P. MapReduce. After having served us well since 2003, today we removed the remaining internal codebase for good. Of course, external users of MR on GCP will continue to be supported with our fully upstream compatible managed Hadoop platform, Dataproc.

John then joked about it and the algorithm:
An update on algorithms used at Google :).

You've served us well, MapReduce. https://t.co/HPP4JXGpzS
John then clarified later on "this is specific to libraries that developers within Google use, so there's no direct effect in search rankings or similar."
(Or a bit clearer: this is specific to libraries that developers within Google use, so there's no direct effect in search rankings or similar)

So don't you worry, MapReduce going away at Google won't help you or hurt you in terms of ranking better or worse.
