Subject [jira] [Created] (MAPREDUCE-3577) Classpath error when installing via separate tarballs
Date Fri, 16 Dec 2011 21:04:31 GMT
Classpath error when installing via separate tarballs

                 Key: MAPREDUCE-3577
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3577
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 0.23.1, 0.24.0
            Reporter: Jonathan Eagles
            Priority: Critical

Classpath error when using the three tarballs to do a hadoop installation. In particular,
HADOOP_PREFIX is guessed incorrectly in yarn-config.sh and passed to hadoop-config.sh. Work
around is to manually set HADOOP_PREFIX.

Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.conf.Configuration
