Subject [jira] [Created] (MAPREDUCE-2485) reinitialize CLASSPATH variable when executing Mapper/Reducer code
Date Wed, 11 May 2011 22:03:47 GMT
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.
