[jira] [Commented] (MESOS-1447) Include Mesos Version in SlaveInfo protobuf

["Benjamin Mahler (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MESOS-1447?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14015660#comment-14015660 ] 

Benjamin Mahler commented on MESOS-1447:
----------------------------------------

{{SlaveInfo}} is generally treated as immutable, and so if a slave is upgraded but recovers its {{SlaveInfo}} from the previous version, this would prove problematic.

It's possible that we could instead add versioning to all protobuf messages (MESOS-986).

> When rolling out a new deployment of mesos across a large cluster, it'd be very useful to see in the Web UI (the Slaves tab) which slave is running which version of Mesos.
> I think this would be fairly easy to achieve, simply adding a new field into the {{SlaveInfo}} protobuf, and setting the value to some kind of version constant (if anyone knows of one that exists, that'd be great).
> Plus a new column in the slaves table on the Web UI.
