Re-adding a dead node in Cassandra 3.9


Our Cassandra cluster uses Cassandra version 3.9. We experienced an issue
for which documentation doesn't seem clear and I'm hoping someone
experienced the same issue and we could use some help.

One of Cassandra node went down and now the host needs to be rebuilt and OS
needs to be reinstalled and then it can be brought back again to be part of
the cluster. The host will have same IP as before. What steps should be
performed for re-adding dead node again? Needless to say, data in the dead
host after it's back is lost.
