Hi! Great video. Some questions/comments: Question 12: Shouldn't we leave 1 node to be the master node? The executors would be only in the worker nodes and so they would be 9*3 (27) Question 21: Spark automatically broadcasts variables in a join operation if the variable size is less than 10Mb Question 25: There is also MEMORY_ONLY_2 and MEMORY_AND_DISK_2 in which each partition is replicated 2 times and stored in 2 different nodes of the cluster.
