We were using 0.7.6 version. And upgraded to 1.2.5 today. We were using OPP (OrderPreservingPartitioner).
OPP throws error when any node join the cluster. Cluster can not be brought up due to this error. After digging little deep, We realized that "peers" column family is defined with key as type "inet". Looks like many other column families in system keyspace has same issue. - I know that OPP is deprecated. Is it that OPP completely unsupported? Is it stated in upgrade instructions or some where? Did we miss it? - I could not find any related discussion or jira records about similar issue.
