Hi Jon,
Thanks for quick reply, I'm a newbie to Cassandra. Even though I made a
mistake in previous mail. you got it right. I'll check what you've said.
Cheers,
Rajith.

Sorting a random set of keys will not help.
False
If you know that you set of keys are on a particular node, then sorting might
help.
True
Two different answers to the same question.
But I doubt that it is a sound practice, given that sets of keys can be moved

Hi,
Thanks for your reply. Our latency currently is 23.618ms. However I
simply read that off one node just now while it wasn't under a load
test. I am going to be able to get a better number after the next test run.
What is a good value for read latency?

Paulo,
If you have large data sizes then the vnodes with hadoop issue is moot. You
will get that many splits with or without vnodes. The issues come when you
don't have a lot of data, so all the extra splits slow everything down to a
crawl because there are 256 times as many tasks created as
Read latency depends on many factors, don't forget physics.
If it meets your requirements, it is good.

Sven,
I've verified there is an issue with jmx authentication in the 3.2.2
release. Thanks for the bug report! Sorry it's giving you issues. The bug
should be fixed in the next release of OpsCenter.

Hi guys,
We currently have 2 datacenters and a ring of 5 Cassandra servers on each
datacenter. We are getting new hardware, and after evaluating them, plan to
upgrade the ring to the new hardware.
Is there any recommended procedure for doing so? This is one of the options we
are considering:

Thanks for your response Rob.
Is step 1 just to reduce downtime for the node? Also, I'm assuming the
initial_token of the new node should be set to be the same as the token of the
old node, or close to that. Eg. [1] in Replacing a Dead Node talks about
setting the new node's intial_token to
