Apache Accumulo for Developers

Book Description

Discover how to build Accumulo, Hadoop, and ZooKeeper clusters from scratch on both Windows and Linux. With this book’s examples-based approach, you’ll learn the painless way through clear instructions and real-world exercises.

  • Shows you how to build Accumulo, Hadoop, and ZooKeeper clusters from scratch on both Windows and Linux

  • Allows you to get hands-on knowledge about how to run Accumulo on Amazon EC2, Google Cloud Platform, Rackspace, and Windows Azure Cloud platforms

  • Packed with practical examples to enable you to manipulate Accumulo with ease

  • In Detail

    Accumulo is a sorted and distributed key/value store designed to handle large amounts of data. Being highly robust and scalable, its performance makes it ideal for real-time data storage. Apache Accumulo is based on Google's BigTable design and is built on top of Apache Hadoop, Zookeeper, and Thrift.

    Apache Accumulo for Developers is your guide to building an Accumulo cluster both as a single-node and multi-node, on-site and in the cloud. Accumulo has been proven to be able to handle petabytes of data, with cell-level security, and real-time analyses so this is your step by step guide in taking full advantage of this power.

    Apache Accumulo for Developers looks at the process of setting up three systems - Hadoop, ZooKeeper, and Accumulo – and configuring, monitoring, and securing them.

    You will learn to connect Accumulo to both Hadoop and ZooKeeper. You will also learn how to monitor the cluster (single-node or multi-node) to find any performance bottlenecks, and then integrate to Amazon EC2, Google Cloud Platform, Rackspace, and Windows Azure. When integrating with these cloud platforms, we will focus on scripting as well.

    You will also learn to troubleshoot clusters with monitoring tools, and use Accumulo cell-level security to secure your data.
