Berenguer Blasi commented on CASSANDRA-17140:
---------------------------------------------
[~jmckenzie] bear in mind we have a java SHA that reliably passes the test and
the next one that reliably fails it. So regardless of the python test issues
imo there is sthg on the java side that can trigger this failure. In other
words, you might rewrite this into a jvm-dtest and still have it fail in the
same way. Wdyt?
