Re: Spark horizontal scaling is not supported in which cluster mode? Ask

[Mark Hamstra]

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.

Spark horizontal scaling is not supported in which cluster mode? Ask

[unk1102]

Hi I came by one Spark question which was about which spark cluster manager
does not support horizontal scalability? Answer options were Mesos, Yarn,
Standalone and local mode. I believe all cluster managers are horizontal
scalable please correct if I am wrong. And I think answer is local mode. Is
it true? Please guide. Thanks in advance.
