             Summary: Reduce CI console output volume
                 Key: CASSANDRA-21624
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-21624
             Project: Apache Cassandra
          Issue Type: Improvement
            Reporter: Brandon Williams


Analysis of a (Jenkins console 
log)[https://ci-cassandra.apache.org/job/Cassandra-5.0/654/] shows ~43MB (41%) 
is two classes of pure-noise output that stream through the controller and are 
buffered in the controller heap per the in-flight sh step:

* Python dtest runs stream the cassandra-driver's reconnect loop at DEBUG 
level. A single flapping dtest-novnode cell produced 14,875 full Python 
tracebacks (~22MB) plus ~80k cassandra.cluster log lines (~11MB), peak 
4.2MB/min.
                                                                                
                                                                                
                                                                            * 
Every forked test JVM logs the complete ant command line including the full 
~17KB classpath ("Forking using command: [...]") = 1,296 lines = 21.4MB, 
identical content every time.
