[jira] [Commented] (HDDS-4008) Recon should fallback to ozone.om.service.ids when the internal service id is not defined.

    [ https://issues.apache.org/jira/browse/HDDS-4008?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17163035#comment-17163035 ] 

Bharat Viswanadham commented on HDDS-4008:
------------------------------------------

[~avijayan]
ozone.om.internal.serviceid is added to let OM what are its internal peers, if the configuration has more than one service ids defined in ozone.om.service.ids. Added as part of HDDS-2536. 

Because in S3G we have failed this. I think all services to behave in same manner, i think we should check if multiple service id's are configured, then we should set mandatorily ozone.om.internal.service.id. In this way, S3G and Recon will behave in the similar manner.

Any thoughts??

> Recon connects to OM via RPC using the "ozone.om.internal.service.id" to get updates. If the above config is not defined, but the ozone.om.service.ids is defined, Recon should use the latter as a fallback. Currently, a single Recon instance supports only 1 OM HA cluster at a time. Hence, if multiple ids are defined, Recon will pick the first.
