creating/dropping keyspaces does not work reliably
--------------------------------------------------
Key: CASSANDRA-2026
URL: https://issues.apache.org/jira/browse/CASSANDRA-2026
Project: Cassandra
Issue Type: Bug
Affects Versions: 0.7.0
Environment: observed on EC2 and real HW
Reporter: Matthew F. Dennis
Priority: Blocker
Creating and/or dropping keyspaces on more than just a few nodes does not
reliably work (observed multiple times on 5, 15 and 40 node clusters. never
observed on single node clusters)
Right after a cluster is booted, importing a schema from yaml works reliably.
However, creating keyspaces (same for dropping keyspaces) via the CLI, either
with -f or by pasting into the window usually does not work (though sometimes
it does). In particular, only some nodes show the new changes while others do
not. ;
Often the changes are only reflected on the node where they were made, but not
on any other node. Most of the time some small subset of the nodes get the
changes, but the majority do not.
Sometimes it takes several attempts to expose the problem. Once it happens the
first time though, it continues to happen reliably on every change after the
problem is first observed.
In most cases all changes were executed from the same seed node. It also
happens when executed from non-seed nodes though.
