Eric Yang commented on HADOOP-6255:
-----------------------------------
Package builder design
For supporting multiple type of packages, this project layout the packaging
source code structure like this:
{noformat}
src/packages/rpm
/deb
/conf-pseudo
{noformat}
rpm - meta data for creating rpm packages. SysV init style startup script is
also included for start up process in Redhat like environment.
deb - meta data for creating debian packages. BSD init style startup script is
also included for start up process in Ubuntu like environment.
conf-pseudo - Configuration template for demo pseudo cluster setup. By default
both rpm, or deb binary package does not startup the system. The purpose of
conf-pseudo is to create a (rpm/deb) package as demonstration of how to setup a
single node cluster and turn on services by configuration.
Software home directory is designed to locate in:
${prefix}/share/${project}
src/packages/update-${project}-env.sh runs in the post installation phase which
creates symlinks and making software structure to map to the proposed layout in
HADOOP-6255
/etc/default/${project}-evn.sh is symlinked to the project environment script.
Hence, project environment variables are shared across projects.
Project build file can override the package path in the build phase:
Sample build.properties
{noformat}
package.prefix=/usr
package.conf.dir=/etc/${project}
package.log.dir=/var/log/${project}
package.pid.dir=/var/log/${project}
{noformat}
For RPM package, it is possible to override location at installation phase by
specifying:
{noformat}
rpm -i ${project}-[version]-[rev].[arch].rpm \
--relocate /usr=/usr/local/hadoop \
--relocate /etc/hadoop=/usr/local/etc/hadoop \
--relocate /var/log/hadoop=/opt/logs/hadoop \
--relocate /var/run/hadoop=/opt/run/hadoop
{noformat}
The same build structure can be apply to both ant or maven build scripts. It
also expandable to include mac native package installer using this design
pattern.
