Apache Hadoop is a widely used distributed data platform. It enables large datasets to be efficiently processed instead of using one large computer to store and process the data. This book will get you started with the Hadoop ecosystem, and introduce you to the main technical topics, including MapReduce, YARN, and HDFS. The book begins with an overview of big data and Apache Hadoop. Then, you will set up a pseudo Hadoop development environment and a multi-node enterprise Hadoop cluster. You will see how the parallel programming paradigm, such as MapReduce, can solve many complex data processing problems. The book also covers the important aspects of the big data software development lifecycle, including quality assurance and control, performance, administration, and monitoring. You will then learn about the Hadoop ecosystem, and tools such as Kafka, Sqoop, Flume, Pig, Hive, and HBase. Finally, you will look at advanced topics, including real time streaming using Apache Storm, and data analytics using Apache Spark. By the end of the book, you will be well versed with different configurations of the Hadoop 3 cluster.

This document defines the test cases for terminal RCS Universal Profile features. It is applicable to the terminals with RCS function. Terminal RCS testing include field testing, lab testing, performance testing and local special test cases. For this document, most of the test cases are related to field testing, and GCF/PTCRB use them as part of the existing certification program. Therefore, for the field test cases the document will refer to TS.11 Annex D RCS section directly. This document also defines RCS test cases for the industry and provides standardized guidance for RCS lab testing, performance testing and other special test cases that are not covered by GCF & PTCRB.
