Horizontal scaling is scaling across multiple, distributed computers (or at least OS instances). Local mode is, therefore, by definition not horizontally scalable since it just uses a configurable number of local threads. If the question actually asked "which cluster manager...?", then I have a small issue with it. Local mode isn't really a cluster manager, since there is no cluster to manage. What it is is one of Spark's scheduling modes.
