spark and hadoop are two big data clusters. Hadoop is a toolkit for distributed computing while Spark is a cluster-computing framework based on Java. Both of them are widely used in Big Data processing. In this topic, we introduce how to balance these two clusters. Spark and Hadoop are two extremely powerful tools for data analysis. A spark is a tool for Big Data processing while Hadoop is a distributed file system. In this article, we will try to explain what they are and how they work.
About spark and hadoop
Spark is a distributed file system and engine for big data processing designed at Apache Software Foundation (ASF). Spark was developed as an open-source project led by Databricks Inc. Spark uses Python programming language and runs on the Hadoop platform and supports streaming analytics over raw data. Spark is a unified cluster computing framework built using Scala, Java, R, etc programming languages. Spark enables developers to build interactive applications running on top of massive clusters of commodity hardware.
Hadoop is a software platform consisting of services and libraries written in various programming languages, including Java, C++, Perl, PHP, Python, Ruby, Go, JavaScript, Shell, etc. Hadoop provides its users with a distributed filesystem, batch computation, and machine learning tools. Its mission is to provide a scalable infrastructure that can analyze petabytes of data in parallel while doing real-time analysis.
what are spark and hadoop
Spark is a high-performance computing system developed by Cloudera. Spark provides a set of tools for application developers to build data-intensive applications using Hadoop, MapReduce, Hive, Pig, Impala, Oozie, Flume, Zookeeper, Hue, Tez, Sqoop, Crunch, Yarn, Fuse, Flume Streaming, HDFS, and HBase. Spark was first released as open-source software in 2010.
Hadoop is a big data framework designed to provide distributed storage and processing of large amounts of data across clusters of commodity servers. Developed by Apache beginning in 2006, Hadoop distributes computations over groups of computers called nodes and stores results back in the cluster’s shared filesystem.to learn more about hadoop-and-spark-balancing-technologies
uses of spark and hadoop
Spark was initially designed to scale out Hadoop’s MapReduce framework. Spark is based on two concepts: RDDs (Resilient Distributed Datasets) and DAGs (Directed Acyclic Graphs). A Resilient distributed dataset or RDD is a collection of objects that are organized into partitions and replicated across multiple machines. Spark provides APIs to manipulate these RDDs and perform actions like transformations, actions, etc.
Hadoop is an open-source project started at Apache Software Foundation in 2007 to provide a scalable file system and distributed computing framework. It was originally developed by Doug Cutting at Yahoo! Inc. and his team while he worked on YARN (Yet Another Resource Negotiator), an abstraction layer over various systems providing resource management services.
Difference spark and hadoop
Spark vs Hadoop – Spark is Google’s open-source framework for big data processing and analysis developed at UC Berkeley and popularized under Apache project name Flume. Spark provides various programming APIs including APIs for machine learning, streaming analytics, graph algorithms, among others. In terms of architecture, Spark is inspired by Bigtable, MapReduce, and Google File System (GFS). Spark runs on top of Hadoop ecosystem. While Spark is written in Java/Scala programming language and supports both in-memory and disk storage; Hadoop on its own is not distributed file system nor does it provide any kind of API. Spark uses YARN and Mesos whereas Hadoop uses HDFS and Map Reduce respectively. Spark vs Hadoop is a great comparison for anyone who wants to know how these two big names in big data world stack up against each other.
