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”.

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!
