reinitialize CLASSPATH variable when executing Mapper/Reducer code ------------------------------------------------------------------
Key: MAPREDUCE-2485 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2485 Project: Hadoop Map/Reduce Issue Type: Improvement Components: pipes Affects Versions: 0.20.2 Environment: Ubuntu 10.04 LTS Reporter: Tom Melendez We're using pipes, and using libhdfs inside our mapper and reducer code. We've determined that we need to execute a putenv call in order for libhdfs to actually have access to the CLASSPATH. Ideally, it should just use the CLASSPATH we set when the job was executed.
