Install Java == 53 54 * 由於 Sun Java Runtime 是執行 Hadoop 必備的工具，因此我們需要安裝 JRE 或 JDK。這裡我們直接安裝 JDK，因為後面寫程式仍舊需要用到 JDK 所提供的編譯器。目前 Ubuntu 9.04 提供的 JDK 套件最新版本為 Sun Java(TM) Development Kit (JDK) 6.06 ，套件名稱為 '''sun-java6-jdk'''。並建議刪除原本的 「 gcj 」 。[[BR]]Since Hadoop is written by Java, Java Runtime Environment are required for execution. We recommand to use Sun Java Development Kit (a.k.a JDK) because we need to compile java source code later. By default Ubuntu 9.04 installed ''gcj'' (java-gcj-compat), but we recommand to remove the package and install Sun Java(TM) Development Kit (JDK) 6.06 ('''sun-java6-jdk''') instead. 58 55 59 56 {{{ … … 62 59 }}} 63 60 64 65 == step 3. 下載安裝Hadoop==61 == Step 3. 下載安裝 Hadoop == 62 == Step 3.
