Installing Hadoop's Eclipse Plugin

Question

I have such a nightmare with the Hadoop\'s Eclipse plugin. First of all the latest Hadoop version (which is 1.1.1) doesn\'t even include the Eclipse plugin jar file. version 1.0

Answer 1

I installed eclipse plugin for hadoop-1.0.4 yesterday with difficulty, and tested it successful.

The reason for plugin not working is that the jar package lost some libs :

• commons-cli-1.2.jar
• commons-configuration-1.6.jar
• jackson-core-asl-1.8.8.jar
• jackson-mapper-asl-1.8.8.jar
• commons-httpclient-3.0.1.jar
• commons-lang-2.4.jar

you could cp this jars from ${hadoop}/lib to ${jar}/lib, and don't forget modifying MANIFEST.

For convenience, I add some code to ${eclipse-plugin-src}/build.xml target jar

and modified MANIFEST.MF in ${eclipse-plugin-src}/META-INF

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

rebuild eclipse-plugin, and HAVE FUN!
