> Key: HADOOP-4926
> URL: https://issues.apache.org/jira/browse/HADOOP-4926
> Project: Hadoop Core
> Issue Type: Bug
> Components: build, test
> Affects Versions: 0.21.0
> Environment: Eclipse 3.2.2, Java 6, Linux Kernel 2.6.24
> Reporter: KP
> Priority: Minor
>
> I am trying to get my development environment up and running. Following
> instructions on Hadoop Wiki + any relevant JIRA Bug Fixes. I downloaded the
> latest trunk (ID 728242) via subversion client in to my eclipse environment.
> Based on instructions posted, I set my ANT_HOME environment variable, ran the
> Ant build task for eclipse-files target succesfully. After refreshing the
> project, I attempted a "build project", which generated the error below.
> Trunk Build fails within "compile-core-test" section:
