Subject [jira] [Commented] (CASSANDRA-10848) Upgrade paging dtests involving deletion flap on CassCI
Date Tue, 02 Aug 2016 13:06:20 GMT


Sylvain Lebresne commented on CASSANDRA-10848:

As the test we're talking about here are paging tests, one thing that could be worth a double
check is CASSANDRA-10880. That is, we should make sure that during upgrades from 2.X to 3.0.x,
we make sure the native protocol version is fixed to version 3 (we should not be using version
4 *even* when talking to 3.0 nodes, and this until the upgrade is over). If it's not guaranteed
by the tests, bad things will happen, including server side error that would break query and
get the {{Requested pages were not delivered before timeout}} error above.

I'm mentioning that because I ran into this with another test today, so it seems that by default
the python driver will try to connect with the max possible version to each node. I'm not
familiar enough with the upgrade test code enough to say if it fixes the protocol version
or not, but if it doesn't, it should.

Here are some examples of tests flapping in this way:
