n pasting in the tokens originally I got the an error, but this was due to
the spacing between the tokens. That error has been resolved I'm just left with
this one?
Any ideas

Jonathan,
Make sure initial tokens have values from back up cluster i.e. 256 tokens. It
is possible to have typo.

Hi again,
Trying to restart my nodes
is so many ways its getting confusing.. what's right?
Can anyone give me some pointers as to the best route to migrate data from
cluster to cluster? The Documentation is so vague and not detailed enough?
Do I copy the snapshots from all the nodes?
Do I just work on one node at a time?
Any suggestion
Hi Bhargav
I had this recently when making changes to a cluster, and It was down to the
Listen_address & broadcast_address. Check your cassandra.yaml and make sure
that your listen_address/broadcast_address and "seeds" values match. Make sure
the Data folder is empty as well.
I would go
The cqlsh image say bad credentials. Just confirming that you have the correct
username/password when logging on.
By turing on authentication I am assuming you mean using the
PasswordAuthenticator instead of the AllowAllAuthenticator in the yaml.

Hi Everyone.
I need the communities help here.
I have attempted

The Consistency will be Quorum, but replication Factor does that need to be 3

@Kurt, You have hit the nail on the head.
Whilst it was an issue with the cassandra-env.sh file, and I fixed this by
overwriting it with the default file, essentially rolling it back, which got me
back in, the larger issue is with the system_auth db it is a REPL factor of 1
and thus as stated

Is there anything I need to do after dropping a column and adding in a column

I recently came across an issue where by my user Keyspace was replicated by 3

authentication, I then lost 2 of my nodes and because authentication wasn’t
replicated I couldn’t log in.
Once I resolved the issue, and got the

Checked the PID is up for cassandra (it is)
Any idea how I can debug the cause of this further?

immediately, does it reconnect?
Anything in the logs?
What you describe is atypical - timeouts on queries can (and will) happen
occasionally under load, but timeout on connect is atypical. Any sign of
networking issues/slowness/dns problems/etc?

Thanks Jeff I have a horrible feeling it may be. I'll get the errors from the
dev guys Monday and email the group, hopefully I can tie this down.
