May 27, 2021 · Apache Spark — which is also open source — is a data processing engine for big data sets. Like Hadoop, Spark splits up large tasks across different nodes. However, it tends to perform faster than Hadoop and it uses random access memory (RAM) to cache and process data instead of a file system.
Apr 30, 2024 · So why would you compare Apache Hadoop vs Apache Spark? The best answer is to understand what each open-source software is used. This will give you a better understanding of which software is best for your existing data architecture.

Hadoop has a native file system called Hadoop Distributed File System (HDFS). HDFS lets Hadoop divide large data blocks into multiple smaller uniform ones. Then, it stores the small data blocks in server groups. Meanwhile, Apache Spark does not have its own native file system. Many organizations run Spark on Hadoop’s file system to store, manage, a...
Hadoop can process large datasets in batches but may be slower. To process data, Hadoop reads the information from external storage and then analyzes and inputs the data to software algorithms. For each data processing step, Hadoop writes the data back to the external storage, which increases latency. Hence, it is unsuitable for real-time processin...
Apache Spark provides a machine learning library called MLlib. Data scientists use MLlib to run regression analysis, classification, and other machine learning tasks. You can also train machine learning models with unstructured and structured data and deploy them for business applications. In contrast, Apache Hadoop does not have built-in machine l...
Apache Hadoop is designed with robust security features to safeguard data. For example, Hadoop uses encryption and access control to prevent unauthorized parties from accessing and manipulating data storage. Apache Spark, however, has limited security protections on its own. According to Apache Software Foundation, you must enable Spark’s security ...
It takes less effort to scale with Hadoop than Spark. If you need more processing power, you can add additional nodes or computers on Hadoop at a reasonable cost. In contrast, scaling the Spark deployments typically requires investing in more RAM. Costs can add up quickly for on-premises infrastructure.
Apache Hadoop is more affordable to set up and run because it uses hard disks for storing and processing data. You can set up Hadoop on standard or low-end computers. Meanwhile, it costs more to process big data with Spark as it uses RAM for in-memory processing. RAM is generally more expensive than a hard disk with equal storage size.
Apr 11, 2024 · When choosing between Apache Hadoop and Apache Spark, it’s important to consider your goals for data analysis. Spark is a good choice if you’re working with machine learning algorithms or large-scale data. If you’re working with giant data sets and want to store and process them, Hadoop is a better option.
Mar 13, 2023 · Here are five key differences between MapReduce vs. Spark: Processing speed: Apache Spark is much faster than Hadoop MapReduce. Data processing paradigm: Hadoop MapReduce is designed for batch processing, while Apache Spark is more suited for real-time data processing and iterative analytics.
