> ------------------------------------------------------------------

> 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.
