Came here with a completely different application but an exact match on build 1.8.0_275-bre_2020_11_16_16_16-b00. After changing Java versions (went to 1.8.0_292) the "fatal error" went away.

It means that you're trying to connect to localhost but either:

  • Cassandra isn't running, or
  • you've set rpc_address to something other than localhost

Run this command to see which IP address CQL port 9042 is bound to:

$ sudo lsof -nPi -sTCP:LISTEN

You need to connect to the IP that the server is listening for clients. Cheers!
