David Capwell commented on CASSANDRA-15685:
-------------------------------------------
[~e.dimitrova] I stopped working on it as I lost my time =(. If you want, feel
free to pick it up! =D
The current state is that the test requires knowing the result of the previous
repair which only happens as a JMX notification, which is lossy; if the
notification is lost, the test fails.
I was planning to append the result to the completion message as we can get
that via polling, for this reason the test could not use the nodetool API but
would need to poll directly (which it does today). I also had a patch a bit
back to fix nodetool to detect failures in case of JMX loosing the error
message, this polling would need to do similar (so should probably be a common
function).
Now, the change to the completion message is better IMO since it also fixes
this for operators (if the notification is lost you don't know if there was a
conflict), since polling will also see the latest message and will report it
correctly.
For now I will unassigned myself.
