Hi, We are in the process of upgrading 1.2 to 2.0.3. We have a four node cluster and we're upgrading one node at a time. After upgrading two of the nodes, we encountered a problem. We observed that if we run nodetool status on the 2.0.3 hosts, they would show 2 nodes down and 2 nodes up. If we run nodetool status on the 1.2 hosts, it would show all nodes up.
Has anyone encountered this? Perhaps I'm missing a step in my upgrade procedure? Please help as this will prevent us from pushing into production. Thanks, Parag
