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.
