the error in the log output looks similar to this

, in the opscenter 5.1.2 , do you configure the username/password same
with the agent and cassandra node too?

I am using opscenter 5.1.2 and just enabled JMX username/password
authentication on my Cassandra cluster. I think I've updated all my opscenter
configs correctly to force the agents to use JMX auth, but it is not working.
I've updated the config under /etc/opscenter/Clusters/[cluster-nam

Still getting inconsistent number of records on consistency ALL and QUORUM.
Following is the output of consistency ALL and QUORUM.
cqlsh:adlog> CONSISTENCY ALL;
Consistency level set to ALL.
cqlsh:adlog> copy adclicklog20150528 (imprid) TO 'adclicklog20150528.csv';
Processed 58000 rows; Write: 306
I have never exported data myself but can u just try setting 'consistency ALL'
on cqlsh before executing command?
Thanks

I am seeing different number of records each time I export a particular
table. There were no writes/reads in this table while exporting the data. I
am not able to understand why it is happening.
Am I missing something here?

I think you should use local_quorum for writes and read consistency of consumer

reads/ writes are good choice.
Knowing when a batch ends is an application level problem nothing to do with

Hello Marcus and thank you for your fast reply.
Yes, we thought about that and indeed it would work. However we really have
writes and reads constraints for respectively producer and consumer datacenters
so we would like to keep all/most access "local".
We don't need synchronization between dat
Hi Fabrice,
Have you considered using "each_quorum" instead of "all"?
Each_quorum will require replies from a quorum of nodes from all
datacenters.
This could be used either:
Producer using each_quorum and consumer local_quroum. (better read
latencies at the cost of write latencies)
or

Hi everyone.
For a project, we use a Cassandra cluster in order to have fast reads/writes on
a large number of (column oriented) generated data.
Until now, we only had 1 datacenter for prototyping.
We now plan to split our cluster in 2 datacenters to meet performance
requirements (the data tra

Well, your column is not called "address", it's called "addresses". It's
your type that is called "address".
