I have an existing javaee application running on JBoss-7 and using postgresql
which I now want to replace with Cassandra-1.1. Hours of Internet search and I
can't find any useful information, example or hint on how to connect Javaee
server i.e JBoss to Cassandra (or might it even be necessary at
OpsCenter just periodically calls describe_ring() on different nodes in the
cluster, so that's how it's getting that information.
Maybe try running nodetool ring on each node in your cluster to make sure
they all have the same view of the ring?

I followed the doc to add the new node. After the nodetool repair, the

Hi,
We have an application with two code paths, one of which uses a secondary
index query and the other, which doesn't. While testing node down scenarios
in our cluster we got a result which surprised (and concerned) me, and I
wanted to find out if the behavior we observed is expected.
Background
Ok, will do. Thanks for the reply.

Perhaps the commit log size tracking for this limit does not, for some
reason, track hints? This se
We are using Cassandra 1.1.0 with an older Pelops version, but I don't
think that in itself is a problem here.
I am getting this exception:

Have a look at Kundera (https://github.com/impetus-opensource/Kundera). It
does provide some sort of support (using Lucene) and allow you to deal with
association in JPA way.

ok sorry I thought columns inside a row had their keys hashed also
So they are just putted as raw bytes
