Overview of this book

Apache Hadoop is one of the most popular big data solutions for distributed storage and for processing large chunks of data. With Hadoop 3, Apache promises to provide a high-performance, more fault-tolerant, and highly efficient big data processing platform, with a focus on improved scalability and increased efficiency. With this guide, you’ll understand advanced concepts of the Hadoop ecosystem tool. You’ll learn how Hadoop works internally, study advanced concepts of different ecosystem tools, discover solutions to real-world use cases, and understand how to secure your cluster. It will then walk you through HDFS, YARN, MapReduce, and Hadoop 3 concepts. You’ll be able to address common challenges like using Kafka efficiently, designing low latency, reliable message delivery Kafka systems, and handling high data volumes. As you advance, you’ll discover how to address major challenges when building an enterprise-grade messaging system, and how to use different stream processing systems along with Kafka to fulfil your enterprise goals. By the end of this book, you’ll have a complete understanding of how components in the Hadoop ecosystem are effectively integrated to implement a fast and reliable data pipeline, and you’ll be equipped to tackle a range of real-world problems in data pipelines.

Hive


Hive is a widely used data warehouse tool on top of Hadoop and plays an important role in running daily batch jobs and business reporting queries by using an execution engine such as MapReduce, Apache Tez, Apache Spark, and so on. It is important to do a benchmark test for it.

TPC-DS

One of the important benchmarking paradigms for Hive is TPC-DS. This benchmarking standard is created especially for big data systems that cater for multiple business needs and different kinds of queries, such as data mining, ad hoc, transaction-oriented, and reporting. You can use the Hortonworks hive-testbench open source package to run TPC-DS benchmark. The following are the steps to execute with HIVE 13:

cd hive-testbench
       ./tpcds-build.sh
  •  Generate tables and load data, as follows:
./tpcds-setup.sh [SCALE_FACTOR][DIRECTORY]

       /* SCALE_FACTOR represents how much data how...
