Sylvain Lebresne commented on CASSANDRA-10785:
----------------------------------------------
While the 2 lines you've posted should obviously not trigger that exception, I
doubt your program contains those 2 lines so you might have a configuration
error somewhere else. In any case, this is almost surely a driver-side error:
either a mis-configuration on your side, or a bug/confusing behavior of the
driver, not a server-side problem.
So I would start by asking for help on the java driver mailing list
([email protected]), maybe joining a complete example that
triggers that exception. If, after working with the java driver maintainers,
you have further evidence that strongly suggest a server-side problem, then
feel free to re-open with that additional evidence. But for now, closing as
this has all the signs of a driver-side problem.
