商品描述
You’ve heard the hype about Hadoop: it runs petabyte–scale data mining tasks insanely fast, it runs gigantic tasks on clouds for absurdly cheap, it’s been heavily committed to by tech giants like IBM, Yahoo!, and the Apache Project, and it’s completely open source (thus free). But what exactly is it, and more importantly, how do you even get a Hadoop cluster up and running?
From Apress, the name you’ve come to trust for hands–on technical knowledge, Pro Hadoop brings you up to speed on Hadoop. You learn the ins and outs of MapReduce; how to structure a cluster, design, and implement the Hadoop file system; and how to build your first cloud–computing tasks using Hadoop. Learn how to let Hadoop take care of distributing and parallelizing your software—you just focus on the code, Hadoop takes care of the rest.
Best of all, you’ll learn from a tech professional who’s been in the Hadoop scene since day one. Written from the perspective of a principal engineer with down–in–the–trenches knowledge of what to do wrong with Hadoop, you learn how to avoid the common, expensive first errors that everyone makes with creating their own Hadoop system or inheriting someone else’s.
Skip the novice stage and the expensive, hard–to–fix mistakes...go straight to seasoned pro on the hottest cloud–computing framework with Pro Hadoop. Your productivity will blow your managers away.
What you’ll learn
- Set up a stand–alone Hadoop cluster the smart way, laid out simply and step by step so you can get up and running quickly to build your next data center, collaborative, data–intensive Internet services application, Software as a Service (SaaS), and more.
- Optimize your Hadoop production tasks like an experienced pro.
- Work with time–proven, bulletproof standard patterns that have been tested and debugged in high–volume production.
- Understand just enough theoretical knowledge to know why something works in Hadoop, without getting bogged down in abstruse walls of theory.
- Get detailed explanations of not only how to do something with Hadoop, but also why, from a front–line coder with years in the Hadoop game.
- Turn someone else’s expensive cluster–wide “wrong” into an orderly, productive "right" with professional–level debugging and testing.
Who is this book for?
IT professionals interested in investigating Hadoop and implementing it in their organizations, and existing Hadoop users who want to deepen their professional toolkits.

商品描述(中文翻譯)
你聽過有關 Hadoop 的炒作:它可以快速執行 PB 級的數據挖掘任務,以極低的成本在雲端上執行龐大的任務,被 IBM、Yahoo! 和 Apache Project 等科技巨頭大力支持,而且完全開源(因此是免費的)。但究竟它是什麼,更重要的是,你如何建立並運行一個 Hadoop 集群呢?
從你所信任的實踐技術知識的 Apress 出版社,《Pro Hadoop》帶你了解 Hadoop。你將學習 MapReduce 的內外知識;如何構建集群,設計和實現 Hadoop 文件系統;以及如何使用 Hadoop 建立你的第一個雲計算任務。學習如何讓 Hadoop 負責分發和並行化你的軟件,你只需專注於編碼,Hadoop 會處理其餘的事情。
最重要的是,你將從一位從 Hadoop 開始就一直在這個領域工作的技術專業人士那裡學習。從一位具有深入了解 Hadoop 的首席工程師的角度撰寫,你將學習如何避免常見且昂貴的錯誤,這些錯誤是每個人在創建自己的 Hadoop 系統或繼承他人系統時都會犯的。
跳過初學者階段和昂貴且難以修復的錯誤...直接成為最熱門的雲計算框架的經驗豐富的專家,通過《Pro Hadoop》提高你的生產力,讓你的管理者大吃一驚。
你將學到什麼:
- 以簡單且逐步的方式設置獨立的 Hadoop 集群,讓你能夠快速啟動並建立下一個數據中心、協作、數據密集型互聯網服務應用、軟件即服務(SaaS)等。
- 像經驗豐富的專家一樣優化你的 Hadoop 生產任務。
- 使用經過時間驗證、經過測試和調試的高容量生產中的標準模式。
- 理解足夠的理論知識,知道為什麼 Hadoop 中的某些事情有效,而不深陷於深奧的理論。
- 獲得詳細的解釋,不僅了解如何在 Hadoop 中執行某些操作,還了解為什麼要這樣做,來自一位在 Hadoop 領域有多年經驗的前線開發人員。
- 將他人昂貴的集群範例轉變為有序、高效的專業級調試和測試。
