4 nodes in the cluster
n1, n2 in dc1
n3, n4 in dc2
dc1 RF=2, dc2 RF=2.
If we run
nodetool repair -hosts 127.0.0.1,127.0.03 -dc "dc1,dc2" multi
on n1.
The -hosts option will be ignored and only the -dc option
will be used to choose which hosts to repair. In this case, n1 to n4
will be repaired.
If user wants to select specific hosts to repair with, there is no need
to specify the -dc option. Use the -hosts option is enough.
Reject the combination and not to surprise the user.
In https://issues.apache.org/jira/browse/CASSANDRA-9876, the same logic
is introduced as well.
