Avro – A data serialization system. (Image credit: Hortonworks) Follow @DataconomyMedia. The Architecture of Hadoop consists of the following Components: HDFS; YARN; HDFS consists of the following components: Name node: Name node is responsible for running the Master daemons. Cloudera Docs. The Hadoop Archive is integrated with the Hadoop file system interface. Hadoop Cluster Architecture. Then, we will be talking about Hadoop data flow task components and how to use them to import and export data into the Hadoop cluster. Components and Architecture Hadoop Distributed File System (HDFS) The design of the Hadoop Distributed File System (HDFS) is based on two types of nodes: a NameNode and multiple DataNodes. A single NameNode manages all the metadata needed to store and retrieve the actual data from the DataNodes. It is a data storage component of Hadoop. Hadoop works on the fundamentals of distributed storage and distributed computation. Apache Hadoop's MapReduce and HDFS components are originally derived from the Google's MapReduce and Google File System (GFS) respectively. It is … >>> Checkout Big Data Tutorial List Hadoop consists of 3 core components : 1. Let's get started with Hadoop components. The Hadoop Distributed File System or the HDFS is a distributed file system that runs on commodity hardware. Files in … We also discussed about the various characteristics of Hadoop along with the impact that a network topology can have on the data processing in the Hadoop System. HDFS (High Distributed File System) It is the storage layer of Hadoop. Eileen has five years’ experience in journalism and editing for a range of online publications. File data in a HAR is stored in multipart files, which are indexed to retain the original separation of data. Eileen McNulty-Holmes – Editor. Hadoop is a software framework developed by the Apache Software Foundation for distributed storage and processing of huge amounts of datasets. Files in a HAR are exposed transparently to users. In future articles, we will see how large files are broken into smaller chunks and distributed to different machines in the cluster, and how parallel processing works using Hadoop. Figure 1 – SSIS Hadoop components within the toolbox In this article, we will briefly explain the Avro and ORC Big Data file formats. tHDFSInput − Reads the data from given hdfs path, puts it into talend schema and then passes it … Then we will compare those Hadoop components with the Hadoop File System Task. Let us now move on to the Architecture of Hadoop cluster. Hadoop archive components. More information about the ever-expanding list of Hadoop components can be found here. Question: 2) (10 Marks) List Ten Apache Project Open Source Components Which Are Widely Used In Hadoop Environments And Explain, In One Sentence, What Each Is Used For – Then - Beside Them, Mention A Proprietary Component Which Accomplishes A Similar Task. This has become the core components of Hadoop. The overview of the Facebook Hadoop cluster is shown as above. The list of Big Data connectors and components in Talend Open Studio is shown below − tHDFSConnection − Used for connecting to HDFS (Hadoop Distributed File System). Here is how the Apache organization describes some of the other components in its Hadoop ecosystem. In this chapter, we discussed about Hadoop components and architecture along with other projects of Hadoop. Hadoop Distributed File System : HDFS is a virtual file system which is scalable, runs on commodity hardware and provides high throughput access to application data. Ambari – A web-based tool for provisioning, managing, and monitoring Apache Hadoop clusters which includes support for Hadoop HDFS, Hadoop MapReduce, Hive, HCatalog, HBase, ZooKeeper, Oozie, Pig, and Sqoop.
