Does Cassandra have an atomic test-or-set operation?
That is, I want to check to see if a key has a value and, if not, set it to
something. But it must be an atomic operation - I can't do a separate fetch

We are experiencing some random hangs while importing data into
Cassandra 0.6.5. The client stack dump is below. We are using Java
Pelops with Thrift r917130. The hang seems random, sometimes millions
of records in, sometimes just a few thousand. It sort of smells like

The cluster looks unbalanced (assuming the Random Partitioner), did you manually assign tokens to the nodes? The section on Token Select here some some tipshttp://wiki.apache.org/cassandra/OperationsOne of the nodes in the cluster is down. Is there anything in the log to explain why ? You may have
Hi,
I need some help about sorting data in the right way from Cassandra.
I have a SuperColumnFamily
SCF: UserData {
UserID (ROW) {
SuperColumnKey1 {

Yes, you are right. For some reason we didn't notice it. The Cassandra
server itself was up still, so the on machine monitoring for the
process didn't go off. nodetool shows it is unresponsive though. We
are still learning how to properly monitor. The machine that went down
ran out of disk space
Hi,
I am using sstable2json to extract row data for debugging some application
issue. I first ran sstablekeys to find the list of keys in the sstable. Then
I use the key to fetch row from sstable. The sstable is from Lucandra
deployment. I get following.
-bash-3.2$ ./sstablekeys
Some quick answers...Cloud Kick monitoring may be helpfulhttps://www.cloudkick.com/monitoring-featuresrpc_timeout_in_ms is the timeout for communication between nodes in the cluster, not clients and the cluster.AFAIK you should be setting timeouts on the Thrift socket. If you get a timeout then
Hi,
I've been battling against some errors that only seem to crop up when I'm
messing around with secondary indices in 0.7-beta2.
Namely I seem to get errors like this start to happen, after I 'delete' a
row in a CF that has a couple of secondary indices on it and then at some
point later try to
