Subject [jira] [Commented] (HDFS-11597) Ozone: Add Ratis management API
Date Tue, 30 May 2017 16:22:05 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11597?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16029641#comment-16029641
] 

Anu Engineer commented on HDFS-11597:
-------------------------------------

> At some point of time, this info will also be written to the local Ratis of SCM.
The question I was trying to ask here was -- What happens if the SCM restarts with this change
? Does SCM remember this Ratis cluster information ? Or do we expect to relearn that info
from heartbeats or something ?
