      Description

      If the $HADOOP_PREFIX/hadoop-dist/target/hadoop-0.23.0-SNAPSHOT.tar.gz tarball is used to distribute hadoop, all of the HADOOP components (HDFS, MAPRED, COMMON) are all under one directory. In this use case, HADOOP_PREFIX should be set and should point to the root directory for all components, and it should not be necessary to set HADOOP_HDFS_HOME, HADOOP_COMMON_HOME, and HADOOP_MAPRED_HOME. However, the $HADOOP_PREFIX/bin/yarn script requires these 3 to be set explicitly in the calling environment or it won't run.

      $HADOOP_PREFIX/bin/yarn should check if $HADOOP_PREFIX is set and, if it is, use that value for the 3 other HADOOP_*_HOME variables.
