Nodetool status / nodetool ring will show an estimated ownership. They estimate 
this by looking at the replication settings of one of the non-system keyspaces 
(presumably those that contain actual data).


If they all have the same replication settings (say, RF=3 in each DC using 
NetworkTopologyStrategy), then the ring/status ownership estimation can be 
reasonably certain it’s correct – whatever value it will calculate is true for 
all keyspaces.

If they differ, then it can print some ownership % from whatever keyspace it 
selects, but that % will be different than if you chose a different keyspace. 
In this case, pass the keyspace as the optional last argument to specify which 
keyspace matters to you.

Subject: what does this Note mean?



Note: Non-system keyspaces don't have the same replication settings, effective 
ownership information is meaningless
