     55 * 基於 !NetBeans 的 MapReduce 開發環境 - [http://www.hadoopstudio.org/ Karmasphere Studio for Hadoop] - Karmasphere Studio for Hadoop is a Sample screenshot MapReduce development environment (IDE) based on !NetBeans.
     56   * STEP 1: 下載 NetBeans IDE 6.8 - [http://bits.netbeans.org/netbeans/6.8/community/fcs/bundles/netbeans-6.8-ml-javase-windows.exe Windows]/[http://bits.netbeans.org/netbeans/6.8/community/fcs/bundles/netbeans-6.8-ml-javase-linux.sh Linux]/[http://bits.netbeans.org/netbeans/6.8/community/fcs/bundles/netbeans-6.8-ml-javase-macosx.dmg Mac OS X]
     57   * STEP 2: 參考 [http://www.hadoopstudio.org/docs/tutorials/nb-tutorial-installation.html 安裝步驟] 文件,設定 JDK 路徑與安裝擴充套件
     58   * STEP 3: 參考 [http://www.hadoopstudio.org/docs/tutorials/nb-tutorial-jobdev-walkthru.html 基本入門] 文件,學習如何使用 Karmasphere Studio for Hadoop 來開發 MapReduce 程式。目前感覺它的 Job Workflow Plugin 介面,對於初學者寫程式來說,還蠻不錯的,因為可以直接看到 !InputFileFormat 的 Key 跟 Value 長怎樣。
     59   * 備註:宣稱 Karmasphere Studio for Hadoop 可以支援跨平台工作部署 - [http://www.hadoopstudio.org/docs/tutorials/tutorial-clients-intro.html Hadoop Clients and Operating System Portability][[br]][[Image(wiki:NCTU100407:10-04-27_Hadoop_Client_Portablility.jpg)]]

    5561 * 如何修改 Hadoop 原始碼:
    5662   * 請根據想要修改的對象,到 hadoop-*/src 找對應的原始碼(Ex. !FairScheduler, !NameNode, !DataNode 等)
