I think the id will be regenerated every time the config will be refreshed. That may be an issue.

Look at ZK stack definition @ https://github.com/apache/ambari/blob/trunk/ambari-server/src/main/resources/common-services/ZOOKEEPER/3.4.5.2.0/package/scripts/zookeeper_server.py? It has some logic to create unique ID. ________________________________ From: Satyanarayana Jampa <[email protected]<mailto:[email protected]>> Sent: Tuesday, July 07, 2015 7:44 AM To: [email protected]<mailto:[email protected]> Subject: custom service - client unique_id property Just wondering, if there is a way to generate a unique_id in the property file for each node, for an custom client service. I mean: I have a custom client service component. I am looking for a way to generate a unique_id in the client property file, for each node it gets installed. Thanks, Satya.
