Difference between Hadoop and Spark

Hadoop is an open-source platform that enables the storing and processing of large amounts of data in a distributed setting across computer clusters. With Hadoop, you can scale from a single server to thousands of devices, each of which is capable of processing and storing data locally. An open-source cluster computing program called Spark is made for quick calculations. It provides a programming interface that supports implicit data parallelism and cluster-wide fault tolerance. The main characteristic of Spark is in-memory cluster computing, which speeds up an application.

Hadoop

  • The Apache software foundation is the owner of the registered trademark Hadoop. It carries out the necessary operation among clusters using a straightforward programming model. Every module in Hadoop is built on the fundamental premise that hardware malfunctions are frequent occurrences and should be handled by the framework.
  • The MapReduce technique is used to execute the application, which process data concurrently across various CPU nodes. In other words, the Hadoop framework is powerful enough to enable the creation of programs that can run on computer clusters and do comprehensive statistical analysis on enormous amounts of data.
  • Hadoop's storage component, the Hadoop Distributed File System, and its processing component, the MapReduce programming model, make up its core. To process data in parallel, Hadoop basically divides files into large chunks and distributes them across clusters. It also transfers package code into nodes.
  • This method will enable faster and more effective dataset processing. Hadoop common, a collection of Java libraries and tools returned by Hadoop modules, is one of the additional Hadoop modules. These libraries contain the necessary Java files and scripts to launch Hadoop and provide an abstraction of the operating system and file system levels. Another module used for managing cluster resources and scheduling jobs is called Hadoop Yarn.

Spark

  • The MapReduce methodology is extended by Spark, which was built on top of the Hadoop MapReduce module to leverage more types of calculations, such as interactive queries and stream processing, efficiently.
  • Spark is not a modified version of Hadoop and has its own cluster administration. Spark makes use of Hadoop in two ways: first, for processing, and second, for storage. Spark only utilizes Hadoop for storage because it handles cluster management on its own.
  • One of the Hadoop subprojects, Spark, was created in 2009 and later made available as open-source software under the BSD licence. By altering some modules and adding other modules, it has many fantastic functions.
  • By lowering the number of read/write operations to the disc, this is made possible. It saves read/write operations by storing the data from intermediate processing in memory. Additionally, Spark comes with built-in Python, Java, or Scala APIs. Consequently, there are various techniques to write applications.

Differences between Spark and Hadoop

Both Hadoop and Spark are well-liked options on the market; let's talk about some of their key distinctions:

  • While Spark is a super-fast cluster computing tool that extends the MapReduce paradigm to effectively use with additional types of computations, Hadoop is an open-source framework that leverages the MapReduce algorithm.
  • While Spark decreases the number of read/write cycles to disc and stores intermediate data in memory, Hadoop's MapReduce approach reads and writes from a disc, slowing down processing performance. Spark stores intermediate data in memory.
  • With Hadoop, developers must manually write each action, but Spark's RDD - Resilient Distributed Dataset - makes programming simple.
  • Unlike Hadoop MapReduce, which only offers a batch engine and is therefore dependent on other engines for a variety of tasks, Spark manages batch, interactive, machine learning, and streaming tasks simultaneously in the same cluster.
  • Hadoop excels in batch processing, while Spark is better suited to real-time data handling.
  • In contrast to Spark, which is a low latency computing framework and can process data interactively, Hadoop is a high latency computing framework without an interactive mode.
  • While Spark can handle real-time data using Spark Streaming, Hadoop MapReduce can only process data in batch mode.
  • For complex flows, Hadoop requires an external job scheduler like Oozie, whereas Spark supports in-memory computing, hence it has its own flow scheduler.
  • When compared in terms of cost, Hadoop is a more affordable alternative, but Spark takes a large amount of RAM to run in-memory, raising the cluster and hence the cost.
