Eric Yang commented on HADOOP-7521:
-----------------------------------
bq. You mean other than the fact that few to no other tarball on the Internet
does this?
Python setup tools and Rubygems both supports this. It is standard practice
with popular Ops tools. Download any python software, and run "python setup.py
bdist_dumb", and it generates a binary tarball with prefix to root level of the
OS. What we propose here is standard.
This change only minimize repetitive tasks in managing $PROJECT_HOME
environment variable. The original tarball design is not scalable for the long
term. Hadoop is a growing eco-system, we should reduce rough edges to improve
adoption.
> bintar created tarball should use a common directory for prefix

> Key: HADOOP-7521
> URL: https://issues.apache.org/jira/browse/HADOOP-7521
> Project: Hadoop Common
> Issue Type: Bug
> Components: build
> Affects Versions: 0.23.0
> Environment: Java 6, Maven, Linux/Mac
> Reporter: Eric Yang
> Assignee: Eric Yang
> Attachments: HADOOP-7521.patch
>
>
> The binary tarball contains the directory structure like:
> {noformat}
> hadoop-common-0.23.0-SNAPSHOT-bin/bin
> /etc/hadoop
> /libexec
> /sbin
> /share/hadoop/common
> {noformat}
> It would be nice to rename the prefix directory to a common directory where
> it is common to all Hadoop stack software. Therefore, user can untar hbase,
> hadoop, zookeeper, pig, hive all into the same location and run from the top
> level directory without manually renaming them to the same directory again.
> By default the prefix directory can be /usr. Hence, it could merge with the
> base OS.
