Remove definition of HADOOP_HOME and HADOOP_PREFIX from hadoop-env.sh.template
------------------------------------------------------------------------------

Key: HADOOP-7388
URL: https://issues.apache.org/jira/browse/HADOOP-7388
Project: Hadoop Common
Issue Type: Improvement
Environment: Java 6, RHEL 5.5
Reporter: Eric Yang
Assignee: Eric Yang
Priority: Trivial


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.

    --------------------------------


    Changing the resolution of this issue to "dup", since the work was done in another jira (HADOOP-7599) and this jira number (HADOOP-7388) is not in CHANGES.txt.
