MapReduce Google Functional programming Facebook All of the following accurately describe Hadoop, EXCEPT ____________ Open-source Real-time Java-based Distributed computing approach Point out the wrong statement. Elastic MapReduce (EMR) is Facebook’s packaged Hadoop offering Amazon Web Service Elastic MapReduce (EMR) is Amazon’s packaged Hadoop offering Scalding is a Scala API on top of Cascading that removes most Java boilerplate All of the mentioned What was Hadoop written in? Java (software platform) Perl Java (programming language) Lua (programming language) Point out the wrong statement. A MapReduce job usually splits the input data-set into independent chunks which are processed by the map tasks in a completely parallel manner The MapReduce framework operates exclusively on <key, value> pairs Applications typically implement the Mapper and Reducer interfaces to provide the map and reduce methods None of the mentioned IBM and ________ have announced a major initiative to use Hadoop to support university courses in distributed computer programming. Google Latitude Android (operating system) Google Variations Google What was Hadoop named after? Creator Doug Cutting’s favorite circus act Cutting’s high school rock band The toy elephant of Cutting’s son A sound Cutting’s laptop made during Hadoop development _______ is a platform for constructing data flows for extract, transform, and load (ETL) processing and analysis of large datasets. Pig Latin Oozie Pig Hive Sun also has the Hadoop Live CD ________ project, which allows running a fully functional Hadoop cluster using a live CD. OpenOffice.org OpenSolaris GNU Linux Facebook Tackles Big Data With _______ based on Hadoop. ‘Project Prism’ ‘Prism’ ‘Project Big’ ‘Project Data’ Point out the correct statement. Hive is not a relational database, but a query engine that supports the parts of SQL specific to querying data Hive is a relational database with SQL support Pig is a relational database with SQL support All of the mentioned _______ function is responsible for consolidating the results produced by each of the Map() functions/tasks. Reduce Map Reducer All of the mentioned Point out the wrong statement. Hardtop processing capabilities are huge and its real advantage lies in the ability to process terabytes & petabytes of data Hadoop uses a programming model called “MapReduce”, all the programs should conform to this model in order to work on the Hadoop platform The programming model, MapReduce, used by Hadoop is difficult to write and test All of the mentioned Point out the wrong statement. Reducer has 2 primary phases Increasing the number of reduces increases the framework overhead, but increases load balancing and lowers the cost of failures It is legal to set the number of reduce-tasks to zero if no reduction is desired The framework groups Reducer inputs by keys (since different mappers may have output the same key) in the sort stage Which of the following genres does Hadoop produce? Distributed file system JAX-RS Java Message Service Relational Database Management System Point out the correct statement. MapReduce tries to place the data and the compute as close as possible Map Task in MapReduce is performed using the Mapper() function Reduce Task in MapReduce is performed using the Map() function All of the mentioned Input to the _______ is the sorted output of the mappers. Reducer Mapper Shuffle All of the mentioned Which of the following platforms does Hadoop run on? Bare metal Debian Cross-platform Unix-like _______ is a utility which allows users to create and run jobs with any executables as the mapper and/or the reducer. Hadoop Strdata Hadoop Streaming Hadoop Stream None of the mentioned ________ is the primary interface for a user to describe a MapReduce job to the Hadoop framework for execution. Map Parameters JobConf MemoryConf None of the mentioned The output of the _______ is not sorted in the Mapreduce framework for Hadoop. Cascader Cascader Scalding None of the mentioned Which of the following phases occur simultaneously? Shuffle and Sort Reduce and Sort Shuffle and Map All of the mentioned ________ is a generalization of the facility provided by the MapReduce framework to collect data output by the Mapper or the Reducer. Partitioner OutputCollector Reporter All of the mentioned ________ hides the limitations of Java behind a powerful and concise Clojure API for Cascading. Scalding HCatalog Cascalog All of the mentioned What license is Hadoop distributed under? Apache License 2.0 Apache License 2.0 Shareware Commercial The number of maps is usually driven by the total size of ____________ outputs inputs tasks None of the mentioned The Pig Latin scripting language is not only a higher-level data flow language but also has operators similar to ____________ SQL JSON XML All of the mentioned The Hadoop list includes the HBase database, the Apache Mahout ________ system, and matrix operations. Machine learning Pattern recognition Statistical classification Artificial intelligence _______ is the most popular high-level Java API in Hadoop Ecosystem Scalding HCatalog Cascalog Cascading According to analysts, for what can traditional IT systems provide a foundation when they’re integrated with big data technologies like Hadoop? Big data management and data mining Data warehousing and business intelligence Management of Hadoop clusters Collecting and storing unstructured data Previous Next Total Question16 Wrong Answer13 Right Answer13
