L1 21 Cluster Configuration V2
Local vs Cluster Mode
In which cases would you use Local Mode?
When you are working with a computer cluster that only has two machines
For distributed computing across a cluster
When you are working with Spark installed on your own laptop
There is never a reason to use local mode since you're not taking advantage of Spark's ability to work on a cluster: you should be using Standalone, YARN, or Mesos
