Hi,
OK we're pretty sure we dropped and re-created the keyspace before
restarting the Cassandra nodes during some testing (we've been migrating to
a new cluster). The keyspace was created via the cli:
create keyspace m7
with placement_strategy = 'NetworkTopologyStrategy'
and strategy_options
Conan,
Good to see I'm not alone in this! I just set up a fresh test cluster. I first
did a fresh install of 1.1.0 and was able to replicate the issue. I then did a
fresh install using 1.0.10 and didn't see the issue. So it looks like rolling
back to 1.0.10 could be the answer for now.

Hi Jeff,
Great! We'll roll back for now, thanks for letting me know.

I (now) understand that the point of this is to get the most recent copy
(at least of the nodes checked) if all replicas simply haven't been
updated to the latest changes. But what about dealing with corruption?
What if the most recent copy is corrupt? With a Zookeeper-based

Hi, I guess you finally solved this issue. I'm experimenting the same one
when trying to upgrade to phpcass 1.0.a.1.
Do you remember how you fixed it or what the problem was exactly ?

Inequalities on secondary indices are always done in memory, so without
at least one EQ on another secondary index you will be loading every row
in the database, which with a massive database isn't a good idea. So by
requiring at least one EQ on an index, you hopefully limit the set of

Check your JMX port in cassandra-env.sh and see if that's open.
Also if you have enabled
JVM_OPTS="$JVM_OPTS -Djava.rmi.server.hostname="
and you are using an ip address for -Djava.rmi.server.hostname make sure that
is the correct ip.

Hello,
Actually there is no problems with JMX, it works fine when node are in
UP state. But after a while cluster goes to inadequate state. For now it
seems that it's a bug of connection handling in Cassandra.

I was thinking of a CF with many many rows with id, type, latitude and

This is hampering our testing of cassandra a lot, and our move to cassandra
1.0.9.
Has anyone seen this before? Should I be trying a different version of
cassandra?

Thank you for the fast answer Tylor, I just discover the existence of
the "ColumnSlice" class. I was using phpcassa for a while and didn't

If I want to get just a column should I do :
$slice = new ColumnSlice('name', 'name');
$result = $cf->get($key, $slice);
or

Version 2 is the default for your connection.
Are you using cqlsh? If so, use the "-3" parameter for version 3...

If you're only fetching a single column and you know its name, use the
second form. However, they should both technically work.
I introduced it because PHP only has positional parameters and most of the
parameters are optional, so having 6 or 10 parameters was annoying when you

I think you need to create the keyspace under the context of a v3
connection. Maybe someone else can confirm?

yes it seems so
