Multi data-center configuration
Hi there,
we are experiencing a problem with a multidatacenter configuration.
We have the following scenario :
We have two data-centers with 3 nodes each.
We have configured seeds like this on each datacenter.
<Seeds>
<Seed>ip1_datacenter_A</Seed>
<Seed>ip2_datacenter_A </Seed>
<Seed>ip3_datacenter_A </Seed>
<Seed>ip1_datacenter_B </Seed>
</Seeds>
We tried both RackAwareStrategy and RackUnAwareStrategy but it seems
that the two data-centers are not communicating at all between them.
Also, with version 4.1 and RackAwareStrategy we are getting an error :
UnsupportedOperationException: Rack-aware bootstrapping not supported
With trunk version we are not getting the error but there is no
communication at all between datacenters.
Can anyone help?
Thanks

Try using just a single seed then.

Hi,
we already tried putting the same seeds list on each DC but it did not work

the seeds list needs to be the same for both DCs -- in fact your whole configuration file should be the same.
put one node from each DC in the seeds list.

Hi,
thank you for your reply.
We tried your suggestion but it did not work.
We are working on version 4.1 and we have already verified that there are no network problems between the datacenters. Also we verified that the nodes inside the same data center are joining each other without any problem.
In attach our configuration files.
I hope you can help us
Thank you
