Which of the following are NOT big data problem(s)? Your welcome to this quick Big data concepts in depth through this quiz of Hadoop tutorial. All of the following accurately describe Hadoop, EXCEPT: can best be described as a programming model used to develop Hadoop-based applications that can process massive amounts of data. For instance, data engineers use the platform to clean, aggregate, and prepare data for analysis, business users use it to run queries on the platform while scientist finds it useful while analyzing patterns from large data set using machine learning algorithms. Question 19: _______  jobs are optimized for scalability but not latency. since Hadoop runs on JVM so, Hadoop can be used in Windows(early version of Hadoop had some Problem) or Linux, but best way to use Hadoop is to run on Linux. What license is Hadoop distributed under ? 8. Which of the following phases occur simultaneously ? (A) Creator Doug Cutting favorite circus act, (D) A sound Cutting laptop made during Hadoop development. Therefore, we have to install a Linux operating system for setting up Hadoop environment. The right number of reduces seems to be : The output of the _______ is not sorted in the Mapreduce framework for Hadoop. Servers can be added or removed from the cluster dynamically and Hadoop continues to operate without interruption. Job Tracker runs on its own JVM process. This way, the entire Hadoop platform works like a system that runs on Java. A ________ node acts as the Slave and is responsible for executing a Task assigned to it by the JobTracker. Question 34: Point out the wrong statement: (A) A MapReduce job usually splits the input data-set into independent chunks which are processed by the map tasks in a completely parallel manner, (B) The MapReduce framework operates exclusively on pairs, (C) Applications typically implement the Mapper and Reducer interfaces to provide the map and reduce methods. It has many similarities with existing distributed file systems. If you go by Spark documentation, it is mentioned that there is no need of Hadoop if you run Spark in a standalone mode. a) RAID b) Standard RAID levels c) ZFS d) Operating system. The Hadoop Distributed File System (HDFS) is a distributed file system designed to run on commodity hardware. It's free to download, use and contribute to, though more and more commercial versions of Hadoop are becoming available (these are often call… We refer to this framework as Hadoop and together with all its components, we call it the Hadoop Ecosystem. The JobTracker is single point of failure for the Hadoop MapReduce service. What does commodity Hardware in Hadoop world mean? Sun also has the Hadoop Live CD ________ project, which allows running a fully functional Hadoop cluster using a live CD. 1. Which of the following genres does Hadoop produce ? You can run a MapReduce job on YARN in a pseudo-distributed mode by setting a few parameters and running ResourceManager daemon and NodeManager daemon in addition. This mode is mainly used for debugging purpose, and it does not support the use of HDFS. Please find the below sections, where Hadoop has been used widely and effectively. Differences Between Cloud Computing vs Hadoop. Q7. With the Mono framework, you should be able to take pretty much any .NET code written on the Windows platform and just run the same binary on Linux. Hadoop, Data Science, Statistics & others . It can be run on local mode (Windows or UNIX based system) or cluster mode. But because there are so many components within this Hadoop ecosystem, it can become really challenging at times to really understand and remember what each component does and where does it fit in in this big world. CDH, Cloudera's open source platform, is the most popular distribution of Hadoop and related projects in the world (with support available via a Cloudera Enterprise subscription). As companies move past the experimental phase with Hadoop, many cite the need for additional capabilities, including: d) Improved security, workload management and SQL support, b) Hadoop 2.0 allows live stream processing of real time data. Question 29: __________ has the world’s largest Hadoop cluster. (A) Bare metal (B) Debian (C) Cross-platform (D) Unix-Like. Map . Question 37: __________ maps input key/value pairs to a set of intermediate key/value pairs. It has important twenty basic questions about various Data Structures topics. maps input key/value pairs to a set of intermediate key/value pairs. I cover four options: Hadoop in Docker - using my Hadoop with .NET Core Docker image to run a Dockerized Hadoop cluster; Question 4: Sun also has the Hadoop Live CD ________ project, which allows running a fully functional Hadoop cluster using a live CD. Question 3: What license is Hadoop distributed under ? Start Your Free Data Science Course. b) Industry standard hardware . So here are my suggestions: Download VMware VMPlayer on your Windows Machine; Download CDH Virtual Machine … Question 24: Hadoop is a framework that works with a variety of related tools. You don't need to run Hadoop from the JAR files though, there are packaged options which make it easy to run Hadoop on Windows. Objective. Question 10: The Hadoop list includes the HBase database, the Apache Mahout ________ system, and matrix operations. b) Hadoop stores data in HDFS and supports data compression/decompression. In recent day terms, cloud computing means storing, accessing data, programs, Application, and files over the internet of the premises rather than on-premises installed on a hard drive. Each slave node is configured with job tracker node location. You can also access HDFS from Windows fairly easily -- while I don't recommend running the Hadoop services on Windows, you can certainly run the DFS client from the Windows platform to copy files in and out of the distributed file system. In case you have an OS other than Linux, you can install a Virtualbox software in it and have Linux inside the Virtualbox. Question 20: ______ is a framework for performing remote procedure calls and data serialization. Hadoop achieves reliability by replicating the data across multiple hosts and hence does not require _____ storage on hosts. Apache Pig Quiz Questions. Hadoop achieves reliability by replicating the data across multiple hosts, and hence does not require _____ storage on hosts. Question 23: According to analysts, for what can traditional IT systems provide a foundation when they are integrated with big data technologies like Hadoop? Question 2: What are the 3v’s of Big Data? d) both (a) and (c) 3. Ans. Common cohorts include __________ . Hadoop does not rely on hardware to provide fault-tolerance and high availability (FTHA), rather Hadoop library itself has been designed to detect and handle failures at the application layer. Which of the following platforms does Hadoop run on ? Which of the following is not the Dameon process that runs on a hadoop cluster ? c) Processing online bank transactions. Question 8: Hadoop achieves reliability by replicating the data across multiple hosts, and hence does not require _____ storage on hosts. 1. Question 30: Facebook Tackles Big Data With _______ based on Hadoop. This is mostly used for the purpose of debugging. Question 38: The number of maps is usually driven by the total size of ______________ . TaskNode. ~ 4. steps of the above instructions are already executed.
