Description

The file structure layout proposed in HADOOP-6255 was designed to remove the need of using HADOOP_HOME environment to locate hadoop bits. The file structure layout should be able to map to /usr or system directories, therefore HADOOP_HOME is renamed to HADOOP_PREFIX to be more concise. HADOOP_PREFIX should not be exported to the user. If the user use hadoop-setup-single-node.sh or hadoop-setup-conf.sh to configure hadoop, the current scripts put HADOOP_PREFIX/HADOOP_HOME in hadoop-env.sh. The config template generation code should remove reference of HADOOP_PREFIX/HADOOP_HOME from hadoop-env.sh.
