Hortonworks Data Platform Data Access (August 29, 2016) Hortonworks Data Platform Data Access (August 29, 2016) docs.cloudera.com HDP Data Access Guide August 29, 2016 Hortonworks Data Platform: Data Access Copyright © 2012-2016 Hortonworks, Inc. Some rights reserved. The Hortonworks Data Platform, powered by Apache Hadoop, is a massively scalable and 100% open source platform for storing, processing and analyzing large volumes of data. It is designed to deal with data from many sources and formats in a very quick, easy and cost-effective manner. The Hortonworks Data Platform consists of the essential set of Apache Hadoop projects including YARN, Hadoop Distributed File System (HDFS), HCatalog, Pig, Hive, HBase, ZooKeeper and Ambari. Hortonworks is the major contributor of code and patches to many of these projects. These projects have been integrated and tested as part of the Hortonworks Data Platform release process and installation and configuration tools have also been included. Unlike other providers of platforms built using Apache Hadoop, Hortonworks contributes 100% of our code back to the Apache Software Foundation. The Hortonworks Data Platform is Apache-licensed and completely open source. We sell only expert technical support, training and partner-enablement services. All of our technology is, and will remain, free and open source. Please visit the Hortonworks Data Platform page for more information on Hortonworks technology.

Prior to Cloudera, Amandeep worked deployed at several large companies . Apache HBase [2] is one such system . It is at Amazon Web Services, where he was part an open source distributed database, modeled around Google Bigtable [5] and is of the Elastic MapReduce team and built the becoming an increasingly popular database choice for applications that need fast initial versions of their hosted HBase product. random access to large amounts of data . It is built atop Apache Hadoop [1] and is [email protected] tightly integrated with it . HBase is very different from traditional relational databases like MySQL, Post- greSQL, Oracle, etc . in how it’s architected and the features that it provides to the applications using it . HBase trades off some of these features for scalability and a flexible schema . This also translates into HBase having a very different data model . Designing HBase tables is a different ballgame as compared to relational database systems . I will introduce you to the basics of HBase table design by explaining the data model and build on that by going into the various concepts at play in designing HBase tables through an example .

  • Final Report CS 5604: Information Storage and Retrieval
    Final Report CS 5604: Information Storage and Retrieval Solr Team Abhinav Kumar, Anand Bangad, Jeff Robertson, Mohit Garg, Shreyas Ramesh, Siyu Mi, Xinyue Wang, Yu Wang January 16, 2018 Instructed by Professor Edward A. Fox Virginia Polytechnic Institute and State University Blacksburg, VA 24061 1 Abstract The Digital Library Research Laboratory (DLRL) has collected over 1.5 billion tweets and millions of webpages for the Integrated Digital Event Archiving and Library (IDEAL) and Global Event Trend Archive Research (GETAR) projects [6]. We are using a 21 node Cloudera Hadoop cluster to store and retrieve this information. One goal of this project is to expand the data collection to include more web archives and geospatial data beyond what previously had been collected. Another important part in this project is optimizing the current system to analyze and allow access to the new data. To accomplish these goals, this project is separated into 6 parts with corresponding teams: Classification (CLA), Collection Management Tweets (CMT), Collection Management Webpages (CMW), Clustering and Topic Analysis (CTA), Front-end (FE), and SOLR. This report describes the work completed by the SOLR team which improves the current searching and storage system. We include the general architecture and an overview of the current system. We present the part that Solr plays within the whole system with more detail. We talk about our goals, procedures, and conclusions on the improvements we made to the current Solr system. This report also describes how we coordinate with other teams to accomplish the project at a higher level. Additionally, we provide manuals for future readers who might need to replicate our experiments.

INTRODUCTION Facebook recently deployed Facebook Messages, its first ever Apache Hadoop [1] is a top-level Apache project that includes user-facing application built on the Apache Hadoop platform. open source implementations of a distributed file system [2] and Apache HBase is a database-like layer built on Hadoop designed MapReduce that were inspired by Googles GFS [5] and to support billions of messages per day. This paper describes the MapReduce [6] projects. The Hadoop ecosystem also includes reasons why Facebook chose Hadoop and HBase over other projects like Apache HBase [4] which is inspired by Googles systems such as Apache Cassandra and Voldemort and discusses BigTable, Apache Hive [3], a data warehouse built on top of the applications requirements for consistency, availability, Hadoop, and Apache ZooKeeper [8], a coordination service for partition tolerance, data model and scalability. We explore the distributed systems. enhancements made to Hadoop to make it a more effective realtime system, the tradeoffs we made while configuring the At Facebook, Hadoop has traditionally been used in conjunction system, and how this solution has significant advantages over the with Hive for storage and analysis of large data sets.

  • Apache Hbase. | 1
    apache hbase. | 1 how hbase works *this is a study guide that was created from lecture videos and is used to help you gain an understanding of how hbase works. HBase Foundations Yahoo released the Hadoop data storage system and Google added HDFS programming interface. HDFS stands for Hadoop Distributed File System and it spreads data across what are called nodes in it’s cluster. The data does not have a schema as it is just document/files. HDFS is schemaless, distributed and fault tolerant. MapReduce is focused on data processing and jobs to write to MapReduce are in Java. The operations of a MapReduce job is to find the data and list tasks that it needs to execute and then execute them. The action of executing is called reducers. A downside is that it is batch oriented, which means you would have to read the entire file of data even if you would like to read a small portion of data. Batch oriented is slow. Hadoop is semistructured data and unstructured data, there is no random access for Hadoop and no transaction support. HBase is also called the Hadoop database and unlike Hadoop or HDFS, it has a schema. There is an in-memory feature that gives you the ability to read information quickly. You can isolate the data you want to analyze. HBase is random access. HBase allows for CRUD, which is Creating a new document, Reading the information into an application or process, Update which will allow you to change the value and Delete where mind movement machine.
