Hello,
I have a Cassandra ring with 4 nodes in 0.8.9 and like to upgrade all nodes to
1.1.5.
It would be great that the upgrade has no downtime or minimal downtime of the
ring.
After I brought down one of the nodes and upgraded it to 1.1.5, when I tried to
bring it up,
the new 1.1.5 node looks good but the rest of three 0.8.9 nodes started
throwing exceptions:
