Subject [jira] [Commented] (CASSANDRA-6971) nodes not catching up to creation of new keyspace
Date Tue, 08 Apr 2014 19:21:14 GMT


Russ Hatch commented on CASSANDRA-6971:

I ran the test 10 times with the patch (modified a bit) and the problem does not seem to be
happening anymore.

> The dtest suite is running a test which creates a 3 node cluster, then adds a keyspace
and column family. For some reason the 3 nodes are not agreeing on the schema version. The
problem is intermittent -- either the nodes all agree on schema quickly, or they seem to stay
stuck in limbo.
> The simplest way to reproduce is to run the dtest (simple_increment_test):
> using nosetests:
> {noformat}
> nosetests -vs
> {noformat}
> If the problem is reproduced nose will return this:
> ProgrammingError: Bad Request: Keyspace 'ks' does not exist
> I am not yet sure if the bug is reproducible outside of the dtest suite.
