around this issue I have recently upgraded datastax-enterprise from 4.8.16 to 5.0.15. We are using password authentication in PlainText format. But below message is continuously coming in logs. , You need to set:
code :
authentication_options:
    plain_text_without_ssl: allow
block  - block the request with an authentication error
warn   - log a warning about the request but allow it to continue (default)
allow  - allow the request without any warning

this will help Cassandra cluster is not cross-version compatible, you can not upgrade a node only, you have to upgrade the cluster. This is a common mistake people tend to do, please see this video here it mentiones this problem, also it is very very useful with lots of good info.

this will help The choice of storing logs in Cassandra is debatable; as the analysis of that data becomes difficult but doable. ELK (Elastic-Logstash-Kibana) or Splunk are more popular choices for log analysis because of their native "text" search support and dashboards.
Having said that, lets look at the problems in hand

I hope this helps . Tracing isn't just limited to CQL. You could enable the same behavior from Java code as well.
Set the tracing flag on the Statement instance. There are various ways depending on how you build it:
code :
// Setter-based:
Statement statement =
  SimpleStatement.newInstance("SELECT * FROM users WHERE id = 1234").setTracing(true);

// Builder-based:
Statement statement =
  SimpleStatement.builder("SELECT * FROM users WHERE id = 1234").withTracing().build();

like below fixes the issue WITH CLUSTERING ORDER BY (time DESC);
Adding this at the end of the table solved the problem for me.
