快速搭建 Hadoop 單機開發環境與雲端叢集架設實務
演講摘要
Hadoop經過七年的開發,終於在 2011 年 12 月釋出 1.0 版本,象徵著 Hadoop 已成熟到能支持企業營運需求。 即便如此,目前 Hadoop 最令人怯步的關鍵在於「不夠友善」。初學者往往第一個要面對的問題是缺乏佈建叢集 所需的背景知識。 在台灣,多數資訊從業人員仍以 Windows 為主要的作業系統。本次演講將跟各位聽眾分享一個名為 Hadoop4Win 的懶人包安裝程式,除了可以作為學習 Hadoop 生態系的第一步外,也可以作為開發 Hadoop 程式的實驗環境。 其次將跟各位介紹如何使用 hiCloud 搭建 Hadoop 叢集。
進行方式
- 以下的展示,將多數跑在 hiCloud 上。為了避免有圖利 hiCloud 之嫌,最後會跟各位介紹國網中心的 EasyCloud 服務。
- 不過這裡要先宣告的是講者跟 hiCloud 沒有利害關係,純粹只是想讓大家有一個標準化的平台可以去試用一些軟體。
- 其次,在試用過 hicloud 之後,我們學習到要提供雲端服務並不容易,同樣地使用雲端服務也不容易。
- 對於開發者來說,若能夠更自動化地進行用 Script 設定好虛擬機器,那才是真正好用的雲端服務。
Background : 申請 hicloud
- 若您是中華電信用戶,您應該可以用 hinet 帳號或者手機登入。
- 若您不是中華電信用戶,請點選「加入會員」
- 如果您看不到操作介面,請安裝 Flash
- Jazz: 非常不開放的架構,採用 Flash 撰寫,效率很差,也阻礙其他人撰寫自動化程式!!'''
- 接著,請點選「雲運算」
- 點選左方「虛擬主機」
- 點選左側上方「申請」
- 選擇要申請的虛擬主機類型,首先,我這次要選取的是 Windows,因為要展示 Hadoop4Win。
Demo 1 : hadoop4win
- 現在我們啟動了一台 Windows 2003 的虛擬機器。(這樣才不會搞爛大會的公用電腦,愛怎麼操就用力操吧~)
- 因為 IE 版本的問題,軟體不太好從 SourceForge 下載,所以我把程式放在底下的 URL
- http://cloud.nchc.org.tw/~jazz/exe
- 我們下載 hadoop4win 0.1.5 的版本,以及 pietty SSH Client 後續我們展示會用到。
Demo 2 : hicloud-hadoop
Demo 3 : Ezilla
