compile-core-test build fails (bad class file error: ExternalMapReduce.class)
-----------------------------------------------------------------------------
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:
