Hi,
In a cassandra cluster, when issueing ring command on every nodes, some can
show all nodes in the cluster but some can only show some other nodes.
All nodes share the same seed list.
And even some of the nodes in the seed list have this problem.
Restarting the problematic nodes won't solve
Chris,
What I have in mind is to use SimpleAuthenticator in conjuction with the
access.properties and passwd.properties.
This use case is actually somewhat personal. I have servers in the AWS
cloud, during development and testing, I may connect from home or wireless
points on the road.
I don't
Jon,
I am experimenting writing 8 million rows into Cassandra and also
experienced some random timeouts, even with 10-second timeout parameter.
How do I avoid such timeout at all cost? (I.e. At this time, my priority is
to finish the end-to-end test. Don't want the program to fail at all.)
This is
Jon,
Looks like this compaction process took 360 seconds. What is it and how do I
avoid it?

Steve,
Looking at the Cassandra docs it appears as though this shouldn't be
too hard to implement, as it should simply involve adding a login
method to the cascal session template. I'll make a ticket in github to
track this , I hope that I have a little more time in the next few
days to
At start up do you see log lines like this
Gossiper.java (line 576) Node /192.168.34.30 is now part of the cluster
Are all the nodes listed?

When this happens to me I have to do a full cluster restart. Even doing a
rolling restart across the cluster doesn’t seem to fix them, all of the nodes
need to be stopped at the same time. After bringing everything back up the ring
is correct.
Does anyone know how a cluster gets into this
Does this happen after you have changed the ring topology, especially
adding nodes?

ZK is way overkill for counters. memcache and redis are much better at the job.

Yes, but not all nodes.
Just the part that the restarting node can show on its ring.

Thanks Stephen.
But still wondering the reason

4 nodes, RF=2, 1 node down.
How can I get an UnavailableException in that scenario?

.QUORUM or .ALL (they are the same with RF=2).
