Turn the logging up to DEBUG, if you want to you can do it just for org.apache.cassandra.service.StorageProxy , and look for… * forwarding counter update of key… when the coordinator is forwarding the counter update * insert writing local & replicate… when a counter mutation is applied locally

It's pretty easy to fix. For background read this page on the wiki http://wiki.apache.org/cassandra/Operations also have a look at the help in the CLI, just type "help;" If you want to reduce your RF use an "update keyspace" statement and change the RF down to 1. You can increase the RF as we

Thanks! This would make sense but I'm not sure it maps to what I'm seeing. Specifically if I start processes that write to each of the three nodes, so I know there is a constant stream of writes to each node, instead of seeing replicate on write on all nodes, I see it only on a single node. It app

2011-08-12 Thread Jeremiah Jordan
You need to wait for the servers to be up again before restarting the next one. nodetool ring on one of the servers you aren't restarting will tell you when it is back up. You can also watch for "Starting up server gossip" in the log file to know when it is starting to join the cluster again.

Restarting servers

2011-08-12 Thread Jason Baker
So restarting cassandra servers has a tendency to cause a lot of exceptions like "MaximumRetryException: Retried 6 times. Last failure was UnavailableException()" and "TApplicationException: Internal error processing batch_mutate" (using pycassa). If I restart the servers too quickly, I get "all s

get_slice failing if replication factor > running nodes

2011-08-12 Thread ian douglas
I'm testing a Cassandra 0.8.1 setup with SimpleCassie for PHP, and my get_slice is failing because when I created the keyspace I set it up like this: create keyspace armorgames with strategy_options=[{replication_factor:2}] and placement_strategy = 'org.apache.cassandra.locator.SimpleStrategy

Installing Brisk on an existing Cassandra cluster?

Hi, Is it possible to add Brisk to an existing Cassandra cluster? The install packages all seem to bundle Cassandra(?) Basically I would like a tar.gz (as I'm on a Mac...) dist of Brisk which I can unpack and deploy on my already running Cassanda cluster. Or is there some tight integration (read

Yes - that ticket was done by Nirmal Ranganathan for the intention of getting support in Cassandra. That's just for a java client though. In the future, I wonder if the CQL driver level is the right place for client encryption. On Aug 11, 2011, at 11:26 PM, Vijay wrote: > https://issues.apach
