Subject [jira] [Created] (HADOOP-7388) Remove definition of HADOOP_HOME and HADOOP_PREFIX from hadoop-env.sh.template

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.
