Eric Yang commented on HDDS-1467:
---------------------------------
AWS and Azure both don't support multicast in their VPC environment. I don't
think ZeroConf can be used on Cloud. It will only work in private data center.
[This link|http://www.zeroconf.org/Rendezvous/txtrecords.html] provides good
information on multicast dns TXT record format. A example code of using
Multicast DNS to advertise ZooKeeper location can be found
[here|https://github.com/macroadster/HMS/blob/master/beacon/src/main/java/org/apache/hms/beacon/Beacon.java].
> Support configless Ozone service management

> Key: HDDS-1467
> URL: https://issues.apache.org/jira/browse/HDDS-1467
> Project: Hadoop Distributed Data Store
> Issue Type: Task
> Reporter: Elek, Marton
> Assignee: Elek, Marton
> Priority: Major
> Attachments: configless.pdf
>
>
> The main goal is to simplify the configuration requirements for Ozone
> components.
> The idea is to merge the service discovery information (which is already
> implemented in a simple form) and merge it with the current ozone-site.xml
> and make it available for all the services.
> Other services (such as OM, s3g) and client can download the current
> configuration from SCM and register the host information.
> Please see the attached design doc for more details.
