cassandra - Cassandra not working after upgrade Ubuntu to 20.04

Question

Cassandra.service is running but couldn't be connected. Cqlsh also not working

标签： cassandracqlshubuntu-20.04

Answer 1

cqlsh doesn't work because Ubuntu 20.04 has Python 3 installed by default, and there is no release of cqlsh that supports it. You need to install Python 2 to use cqlsh

Cassandra requires Java 8 - check that you have OpenJDK 8 installed (by default Java 11 is installed), and that Cassandra is configured to use it.

P.S. These problems with versions will be fixed with release of the Cassandra 4.0
