Looks like the cause of the error was because of not specifying num_tokens in the cassandra.yaml file. I was under the impression that setting a value of num_tokens will override the initial_token value . Looks like we need to set num_tokens to 1 to get around this error. Not specifying anything causes the above error.

I tried both a rolling upgrade while other nodes are on 1.1.10 version and also while all nodes in the cluster were shutdown and just the new version cassandra node coming up. The 1.1.10 version nodes see the 1.2.4 version node up but the 1.2.4 version node crashes a few seconds after the start up. I see the following exception in the logs when the 1.2.4 node starts up. …… INFO 03:03:26,399 Log replay complete, 13 replayed mutations INFO 03:03:26,631 Cassandra version: 1.2.4-SNAPSHOT INFO 03:03:26,631 Thrift API version: 19.35.0 INFO 03:03:26,632 CQL supported versions: 2.0.0,3.0.1 (default: 3.0.1) INFO 03:03:26,660 Starting up server gossip INFO 03:03:26,671 Enqueuing flush of Memtable-local@1284117703(253/253 serialized/live bytes, 9 ops) INFO 03:03:26,672 Writing Memtable-local@1284117703(253/253 serialized/live bytes, 9 ops) INFO 03:03:26,676 Completed flushing /data/cassandra/data/system/local/system-local-ib-4-Data.db (250 bytes) for commitlog position ReplayPosition(segmentId=1371956606055, position=50387) INFO 03:03:26,684 Compacting [SSTableReader(path='/data/cassandra/data/system/local/system-local-ib-3-Data.db'), SSTableReader(path='/data/cassandra/data/system/local/system-local-ib-2-Data.db'), SSTableReader(path='/data/cassandra/data/system/local/system-local-ib-4-Data.db'), SSTableReader(path='/data/cassandra/data/system/local/system-local-ib-1-Data.db')] INFO 03:03:26,706 Compacted 4 sstables to [/data/cassandra/data/system/local/system-local-ib-5,]. 852 bytes to 457 (~53% of original) in 19ms = 0.022938MB/s. 4 total rows, 1 unique.
