I just had a strange issue with a solandra ring. We had a two node test cluster running in one data center and then started up a second 5 node cluster in another data center. The seed in the first DC was in that DC and the seed in the second DC was in the second DC, so the two rings should not have talked to each other. However, they did. The old nodes joined the new cluster. WTF?
Anyone with any ideas why?
