Means Hadoop provides us 2 main benefits with the cost one is it’s open-source means free to use and the other is that it uses commodity hardware which is also inexpensive. The Hadoop Distributed File System (HDFS) is a distributed file system. In case a particular machine within the cluster fails then the Hadoop network replaces that particular machine with another machine. 1. Apache Hadoop offers a scalable, flexible and reliable distributed computing big data framework for a cluster of systems with storage capacity and local computing power by leveraging commodity hardware. What is Yarn in Hadoop? In this section of the features of Hadoop, let us discuss various key features of Hadoop. In other words, it can be implemented on any single hardware. Some of the main features of Hadoop are as follows, Easily Scalable. It is best-suited for Big Data analysis; Typically, Big Data has an unstructured and distributed nature. This is a huge feature of Hadoop. Then why Hadoop is so popular among all of them. It is most powerful big data tool in the market because of its features. It can be implemented on simple hardwar… However, the user access it like a single large computer. Each of these can be running a different version and a different flavour of operating system. Once this feature has been properly configured on a cluster then the admin need not worry about it. 2. With this flexibility, Hadoop can be used with log processing, Data Warehousing, Fraud detection, etc. For example, consider a cluster is made up of four nodes. Unlike traditional systems, Hadoop enables multiple types of analytic workloads to run on the same data, at the same time, at massive scale on industry-standard hardware. Overview. Hadoop cluster is Highly Scalable There are lots of other tools also available in the Market like HPCC developed by LexisNexis Risk Solution, Storm, Qubole, Cassandra, Statwing, CouchDB, Pentaho, Openrefine, Flink, etc. This process saves a lot of time and bandwidth. Companies are investing big in it and it will become an in-demand skill in the future. Similarly YARN does not hit the scalability bottlenecks which was the case with traditional MapReduce paradigm. It is also one of the most important features offered by the Hadoop framework. Since it is an open-source project the source-code is available online for anyone to understand it or make some modifications as per their industry requirement. This means a Hadoop cluster can be made up of millions of nodes. Hadoop is a highly scalable model. Hadoop is designed in such a way that it can deal with any kind of dataset like structured(MySql Data), Semi-Structured(XML, JSON), Un-structured (Images and Videos) very efficiently. Therefore, the data can be processed simultaneously across all the nodes in the cluster. Apache Hadoop is that the hottest and powerful big data tool, Hadoop provides the world’s most reliable storage layer. In Hadoop data is replicated on various DataNodes in a Hadoop cluster which ensures the availability of data if somehow any of your systems got crashed. It is one of the most important features of Hadoop. Hadoop is the framework which allows the distributed processing of large data sets across the clusters of commodity computers using a simple programming model. How Does Namenode Handles Datanode Failure in Hadoop Distributed File System? The High availability feature of Hadoop ensures the availability of data even during NameNode or DataNode failure. Hadoop will store massively online generated data, store, analyze and provide the result to the digital marketing companies. The concept of Data Locality is used to make Hadoop processing fast. Hadoop follows a Master Slave architecture for the transformation and analysis of large datasets using Hadoop MapReduce paradigm. This saves a lot of time. Given below are the Features of Hadoop: 1. Experience. Counters There are often things you would … - Selection from Hadoop: The Definitive Guide, 3rd Edition [Book] What are the hidden features of Hadoop MapReduce that every developer should be aware of? Today tons of Companies are adopting Hadoop Big Data tools to solve their Big Data queries and their customer market segments. This means it can easily process any kind of data independent of its structure which makes it highly flexible. Hadoop is a framework written in java with some code in C and Shell Script that works over the collection of various simple commodity hardware to deal with the large dataset using a very basic level programming model. Yarn was initially named MapReduce 2 since it powered up the MapReduce of Hadoop 1.0 by addressing its downsides and enabling the Hadoop ecosystem to perform well for the modern challenges. Our trainers are very well familiar with Hadoop. In Hadoop 3 we can simply use –daemon start to start a daemon, –daemon stop to stop a daemon, and –daemon status to set $? Users are encouraged to read the full set of release notes. It supports a large cluster of nodes. Hadoop framework is a cost effective system, that is, it does not require any expensive or specialized hardware in order to be implemented. Hadoop is Open Source. In this section of the features of Hadoop, allow us to discuss various key features of Hadoop. Thus, data will be available and accessible to the user even during a machine crash.
