Summary: Provide systemd service unit files
Key: BIGTOP-4182
URL: https://issues.apache.org/jira/browse/BIGTOP-4182
Project: Bigtop
Issue Type: Improvement
Reporter: Masahiro Tanaka
Currently we do not provide systemd service files for all components. We
provide init scripts, which are converted to service files by automatic
conversion by systemd-sysv-generator.
We propose to provide service files in order to implement fine tuning for
systemd in the future.
An example of service file generated by {{ systemd-sysv-generator }} (datanode)
