----------------------------------
[~swagle] Hi, I think the following code use the ipaddress of datanode and the
code [~adoroszlai] has found out were the root cause. I will submit a PR.
https://github.com/apache/hadoop-ozone/blob/master/hadoop-hdds/client/src/main/java/org/apache/hadoop/hdds/scm/XceiverClientGrpc.java#L173
> Datanode should use hostname in place of ip addresses to allow DN's to work
> when ipaddress change
