5 Now we all need to store and process BIG DATA!!

6

7 Features of Hadoop... Hadoop 這套軟體的特色是... 海量 Vast Amounts of Data – 擁有儲存與處理大量資料的能力 – Capability to STORE and PROCESS vast amounts of data. 經濟 Cost Efficiency – 可以用在由一般 PC 所架設的叢集環境內 – Based on large clusters built of commodity hardware. 效率 Parallel Performance – 透過分散式檔案系統的幫助，以致得到快速的回應 – With the help of HDFS, Hadoop have better performance. 可靠 Robustness – 當某節點發生錯誤，能即時自動取得備份資料及佈署運算資源 – Robustness to add and remove computing and storage resource without shutdown entire system.

8 Which companies are powered by Hadoop ?? 有哪些公司在用 Hadoop 這套軟體 ?? Yahoo is the key contributor currently. IBM and Google teach Hadoop in universities … The New York Times used 100 Amazon EC2 instances and a Hadoop application to process 4TB of raw image TIFF data (stored in S3) into 11 million finished PDFs in the space of 24 hours at a computation cost of about $240 (not including bandwidth) – from Facebook Tweeter

9 Hadoop in production run.... 商業運轉中的 Hadoop 應用.... February 19, 2008 Yahoo! Launches World's Largest Hadoop Production Application

10 You can store and process BIG DATA via Large Cluster!!

Common method to deploy Cluster in Labs 1. Setup one Templatemachine Templatemachine 2. Cloning tomultiplemachine tomultiplemachine 3. Configure Settings↓ 4. Install JobScheduler↓ 5. Running Benchmark 3. Configure Settings↓ 4. Install JobScheduler↓ 5. Running Benchmark

Challenges of common method in Labs Upgrade Software ? Add New User Account ? Configuration Syncronization How to share user data ?

How to deploy Nodes ?!

If you need to deploy in Cloud - try Puppet 如果要在 Amazon EC2 上佈署 Hadoop 等軟體，可以考慮 Puppet 因為作業系統已由虛擬機器的範本裝好了，只能用「有碟」的作法！

17 Can I install ONE server to deploy hadoop cluster ?

Yes, use DRBL to deploy Hadoop Need to build new debian packages drbl-hadoop – Mounting local disk for HDFS and MapReduce svn co hadoop-register – for multiuser registration and ssh client svn co

About hadoop.nchc.org.tw DRBL Server x 1 Node (hadoop) DRBL Client x 20 Nodes (hadoop101~hadoop120) Powered by Debian Squeeze 6.0.4

使用者註冊頁面 Hadoop-Register Powered by Zterm

系統狀態監控 Ganglia 採用自由軟體 Ganglia 來蒐集電腦叢集的負載狀態

DRBL+Hadoop=Haduzilla 黑肚龍系統架構

23 Can you help me to deploy my own multiuser hadoop cluster like hadoop.nchc.org.tw ?

In Year 2009, I released DRBL- Hadoop Live CD 舊影片： 下載點：
