[jira] [Comment Edited] (HDDS-3936) OM client failover ignores
suggested leader info
[ https://issues.apache.org/jira/browse/HDDS-3936?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17153815#comment-17153815 ]

One idea is to send along hostname also, and use that during failover, so in the case of mismatch between client and server also it can work.
And also right now getServiceInfo returns nodeID and hostName, need to see if can we use that info during failOver, (if there is any mismatch between client and server)
