Subject Re: Unexpected error while refreshing token map, keeping previous version (IllegalArgumentException: Multiple entries with same key ?
Date Thu, 20 Jun 2019 15:20:34 GMT
One thing that strikes me is that the endpoint reported is '127.0.0.1'.  Is
it possible that you have rpc_address set to 127.0.0.1 on each of your
three nodes in cassandra.yaml?  The driver uses the system.peers table to
identify nodes in the cluster and associates them by rpc_address.  Can you
verify this by executing 'select peer, rpc_address from system.peers' to
see what is being reported as the rpc_address and let me know?

In any case, the driver should probably handle this better, I'll create a
driver ticket.

Thanks,
Andy
