Editor to share with you how to compile the eclipse plug-in for hadoop1.x. I hope you will get something after reading this article. Let's discuss it together.

Note: the following operations are based on Hadoop-1.2.1,Eclipse Luna,Win7 64-bit

1. Import the project of hadoop eclipse plug-in into Eclipse. The plug-in source code directory is as follows:

D:\ Lab\ lib\ hadoop\ hadoop-1.2.1\ src\ contrib\ eclipse-plugin

2. Configuration project dependence

3. Prepare the configuration file of ant

D:\ Lab\ lib\ hadoop\ hadoop-1.2.1\ src\ contrib\ build-contrib.xml

Copy the above build-contrib.xml to the project directory and modify the contents of the file. The details are as follows:

4. Modify build.xml

5. Modify MENIFEST.MF to add some dependent jar to Bundule-ClassPath.

Bundle-ClassPath: classes/, D:/Lab/lib/hadoop/hadoop-1.2.1/lib/hadoop-core-1.2.1.jar, D:/Lab/lib/hadoop/hadoop-1.2.1/lib/commons-cli-1.2.jar, D:/Lab/lib/hadoop/hadoop-1.2.1/lib/commons-configuration-1.6.jar, D:/Lab/lib/hadoop/hadoop-1.2.1/lib/commons-httpclient-3.0.1.jar D:/Lab/lib/hadoop/hadoop-1.2.1/lib/commons-lang-2.4.jar, D:/Lab/lib/hadoop/hadoop-1.2.1/lib/jackson-core-asl-1.8.8.jar, D:/Lab/lib/hadoop/hadoop-1.2.1/lib/jackson-mapper-asl-1.8.8.jar

5. Add Ant Builder.

6. Compilation

Build Project in the Project menu

7. Running result
