Flume supports three modes of operation: single node, pseudodistributed,

and fully distributed.

Single node is useful for basic testing and getting up and running quickly

Pseudo-distributed is a more production like environment that lets us build more complicated flows while testing on a single physical machine

Fully distributed is the mode that run in for production. The fully distributed

mode offers two further sub-modes: a standalone mode with a single

master and a distributed mode with multiple masters.
