So far, I haven't found a place on Datastax documentation website that sums this up. Can I easily check the version some other way on a server?
Open cqlsh and type show VERSION
.
This gives all the versions of cqlsh, DSE, Cassandra etc.
admin@cqlsh> SELECT cql_version FROM system.local;
cql_version
-------------
3.4.0
Also, nodetool version
shows the Cassandra version
