Summary: Add support for systemd conf file in Zookeeper
Key: BIGTOP-3370
URL: https://issues.apache.org/jira/browse/BIGTOP-3370
Project: Bigtop
Issue Type: Improvement
Reporter: Heather Lemon
This feature request is a follow on from this previous jira issue:
#https://issues.apache.org/jira/browse/ZOOKEEPER-2095 to add systemd support
for Zookeeper. There is an attached patch file in the jira, however I believe
we only need the systemd startup script.
Tested on distributed 3-node ubuntu instance with systemd zk.service,
instructions from here:
