Question

Pls do fast i will give u like

big data, spark rdd, cluster
R1 = sc.textFile(file.csv, 4)
R2=R1.filter(.....)
R3=R2.map(.....)
R4=R3.filter(.....)
R5=R1.filter(......)
R6=R5.map(.....)
a) Every instruction given in above snippet requires 2 seconds for execution. If there are 4
cores available in the Spark clusters, what will total execution time?
Answer:
Zero seconds, no action called, so no execution
b) Every instruction given in above snippet requires 2 seconds for execution. If there are 6
cores available in the Spark clusters, what will happen to the program execution time?
Answer:
No change, no execution will happen as no action called
c) If the following two instructions are added into the above program assuming number of
cores as 4, what will be the execution time?
R4.count()
R6.count()
Answer:
10 seconds for first lineage
8 seconds for second lineage
please explain the formula for calculating
