Cassandra version

[goldforg]

I am interested what Cassandra version I should use.
I had Cassandra version 4.0-rc1 on my worker nodes and I got error message in transformation step something like this.

22/04/27 14:33:02 WARN pool.ChannelPool: [s0|/192.168.66.153:9042] Fatal error while initializing pool, forcing the node down (UnsupportedProtocolVersionException: [/192.168.66.153:9042] Host does not support protocol version V5)
22/04/27 14:33:02 WARN pool.ChannelPool: [s0|/192.168.66.114:9042] Fatal error while initializing pool, forcing the node down (UnsupportedProtocolVersionException: [/192.168.66.114:9042] Host does not support protocol version V5)

For this I understood I had to downgrade cassandra version to 3.0.26.
Afterwards I had to clean up the /var/lib/cassandra/data/* folder

I re-run the second step ingest and now I get error, because cassandra 3 does not support PER PARTITION keyword.

Unlocking data directory.
