Re: Cassandra Different cluster gossiping to each other

[Harikrishnan Pillai]

This is possible if some of the nodes are available in system peer table of the 
other cluster.this usually occurs when we decommission nodes from one cluster 
and add to another cluster.also make sure that before adding a node newly to a 
cluster all data in drives are properly wiped out .

You have somehow mixed seeds (or re-used IP addresses). The good news is that 
different cluster names have prevented you from pretty ugly data issues. Check 
your seed lists and system.peers on your hosts for IPs belonging to the wrong 
cluster, and remove them.
