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.

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 · Hadoop and Spark are both smart options for big-scale data processing. Learn more about the similarities and differences between Hadoop versus Spark, when to use Spark versus Hadoop, and how to choose between Apache Hadoop and Apache Spark.
Feb 6, 2023 · Apache Spark is a lightning-fast unified analytics engine used for cluster computing for large data sets like BigData and Hadoop with the aim to run programs parallel across multiple nodes. It is a combination of multiple stack libraries such as SQL and Dataframes, GraphX, MLlib, and Spark Streaming.
Jul 28, 2023 · For most implementations, Apache Spark will be significantly faster than Apache Hadoop. Built for speed, Apache Spark may outcompete Apache Hadoop by nearly 100 times the speed.
Apr 30, 2024 · Published: April 30, 2024. Time to read: 7 minutes. Apache Hadoop and Apache Spark are big data processing frameworks. The former arrived when big data lived in the data center, while the latter emerged to meet the needs of data scientists processing data in the cloud.
