error while trying to run MapReduce job using eclipse Indigo

Question

I am trying to run MapReduce jobs using hadoop-eclipse plugin with Eclipse Indigo, but I am getting the following error:

Error: failure to login

While looking for some help, I found there is a problem with Hadoop-0.20.203.0, so I tried Hadoop-0.20.205.0 as the issues are fixed in this version.

I am still facing the same problem. Am I missing something or making a mistake?

Sorry for my poor English, as your question has no more detail, I guess that you meet the same problme as me, if so, the following link resolved my problem, pls. pay attention to step "4".

http://hi.baidu.com/wangyucao1989/blog/item/279cef87c4b37c34c75cc315.html

Sorry for that is a page in Chinese. It said the problem is because the file hadoop-eclipse-plugin-0.20.203.0.jar lost 5 files "commons-configuration-1.6.jar , commons-httpclient-3.0.1.jar , commons-lang-2.4.jar , jackson-core-asl-1.0.1.jar 和 jackson-mapper-asl-1.0.1.jar ". You should: Extract the "hadoop-eclipse-plugin-0.20.203.0.jar", Add the 5 files into "hadoop-eclipse-plugin-0.20.203.0\lib" , Modify "hadoop-eclipse-plugin-0.20.203.0\META-INF\MANIFEST.MF" (modify the Bundle-ClassPath). Re 'jar' the package and replace the old "hadoop-eclipse-plugin-0.20.203.0.jar".

The os the page referred is linux, my os is Win7.

good luck!

Instead of going for adding plugin u can just add the required libraries in eclipse and do your programming.
here is the list of library u will need. These files exists with the Apache hadoop distribution in lib folder.

• hadoop-core-1.1.2.jar
• log4j-1.2.15.jar
• jackson-mapper-asl-1.8.8.jar
• jackson-core-asl-1.8.8.jar
• commons-logging-api-1.0.4.jar
• commons-logging-1.1.1.jar
• commons-lang-2.4.jar
• commons-httpclient-3.0.1.jar
• commons-configuration-1.6.jar
