Ekaterina Dimitrova commented on CASSANDRA-16644:
-------------------------------------------------
I fixed the CCM patch
[here|https://github.com/ekaterinadimitrova2/ccm/commit/60515b59cc59dd4ac500321f6b6b3a8818ed7f88],
I had a small mistake due to which the TAIL was always empty. Now it is fine,
you can see where the method stopped reading from the log.
You can see in the latest
[runs|https://app.circleci.com/pipelines/github/ekaterinadimitrova2/cassandra/808/workflows/737073ba-0e24-4a1f-9cdb-fffbef041a73/jobs/4568/tests#failed-test-0]
I submitted with lower timeout, the message we look for is in the log but
_watch_log_for_ method doesn't find the message; we just reached the timeout
earlier before reaching the message in the log which we read line by line.
I am +1 on the raised timeout plus updated CCM debug message.
