> Please read [https://github.com/apache/ozone/pull/8934#issue-3312911733] for context.
> This jira specifically fixes the following part of the problem:
> Since the dead maintenance node is removed from topology, checking its containers for mis replication will fail, again because the node is removed from topology. I haven't reprod this, I just got this from reading the logic in validateContainerPlacement. HDFS gets around this by using node's network location that is held in memory in the node's object instead of using the network topology. I think we could do something similar in ozone.
> Also consider the suggestion given here as a fix (second point): [https://github.com/apache/ozone/pull/8934#issuecomment-3189172581]
