I just configured a 3 node cluster in this way and was able to reproduce
the warning message:
cqlsh> select peer, rpc_address from system.peers;
peer | rpc_address
---+-
127.0.0.3 | 127.0.0.1
127.0.0.2 | 127.0.0.1
(2 rows)
cqlsh> select rpc_address from system.lo
Thank you for the information !

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

There’s a reasonable chance this is a bug in the Datastax driver - may want to
start there when debugging .
It’s also just a warn, and the two entries with the same token are the same
endpoint which doesn’t seem concerning to me, but I don’t know the Datastax
driver that well

It appears that no such warning is issued if I connected to Cassandra from a
remote server, not locally.

Hello,
Assuming you nodes are out for a while and you don't need the data after 60
days (or cannot get it anyway), the way to fix this is to force the node
out. I would try, in this order:
- nodetool removenode HOSTID
- nodetool removenode force
These 2 might really not work at this stage, but i
Hello,
This looks more like a JanusGraph question. Also I would rather try in the

I never saw anyone here or elsewhere using JanusGraph, after searching I
only found 4 threads about it here. Thus I think I think even people

Hello Maxim.
I think you won't be able to do what you want this way. Collections are
supposed to be (ideally small) sets of data that you'll always read

the latest versions, but I did not hear about new design for collecti

Hey!
I’ve just configured a test 3-node Cassandra cluster and run very trivial java
test against it.
I see the following warning from java-driver on each CqlSession initialization:

My bad on date formatting, it should have been : %Y/%m/%d
Otherwise the SSTables aren't ordered properly.
You have 2 SSTables that claim to cover timestamps from 1940 to 2262, which
is weird.
Aside from that, you have big overlaps all over the SSTables, so that's
probably why your tombstones are s
