Infrastructure

I found there are some duplicated replicas in the system metadata:
https://cn.dataone.org/cn/v2/meta/resource_map_urn:uuid:1e97bd1f-76fd-4fd2-bbe7-3fd2b788a3bb
You see, the cn and arctic nodes are duplicated.

I ran this query:
select distinct guid from smreplicationstatus group by guid, member_node having count(*) >1;

and got 2407 rows. This means we have 2407 has the issue.
