- If you’re working with giant data sets and want to store and process them, Hadoop is a better option. Hadoop is more cost-effective and easily scalable than Spark. To increase Hadoop's processing capacity, you need only add more computers. However, Spark requires more RAM to increase its in-memory processing capabilities, which can be expensive.

What are the benefits of using Hadoop?
To store, manage, and process big data, Apache Hadoop separates datasets into smaller subsets or partitions. It then stores the partitions over a distributed network of servers. Likewise, Apache Spark processes and analyzes big data over distributed nodes to provide business insights.
Key differences: Apache Spark vs. Apache Hadoop. Outside of the differences in the design of Spark and Hadoop MapReduce, many organizations have found these big data frameworks to be complimentary, using them together to solve a broader business challenge.
Aug 16, 2023 · We used Apache Spark 3.4 and Hadoop 3.3.1 versions for our workload. With default parameters, the job took 10 minutes to complete, with an average CPU utilization of 50%. We observed the CPU utilization was low, and were looking for ways to improve it, bringing the job completion time down in the process.
