Subject [jira] Commented: (HADOOP-6255) Create an rpm integration project
Date Fri, 11 Feb 2011 21:50:57 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6255?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12993721#comment-12993721
] 

Eric Yang commented on HADOOP-6255:
-----------------------------------

$PREFIX/var/lib is configurable by xml configuration.  User has the full control of where
to put this directory for multi-node deployment.  For single node deployment, I put in /var/lib/hadoop
for good practice.

For $PREFIX/lib, the native hadoop c libraries goes here.  For now, $PREFIX/share/hadoop is
chosen for backward compatibility reason of HADOOP_HOME.  Once we moved to maven and have
separated jar file for each module, it will be easier to modularize and put jar files into
/usr/lib/hadoop or /usr/lib/java/hadoop.

I chose to symlink /etc/hadoop to /usr/share/hadoop/conf for backward compatibility reason
of HADOOP_HOME.  For the same reason that /etc/grub.conf is symlinked to /boot/grub/grub.conf.
 I could make the packaging system do the reverse, if hadoop community prefers this.
