Aaron, thanks again for your help.
In the first step, the user add the keyspace 'foo'. In the server side, it
is modified prefixing the user's domain name if there is one. So after that,
there is no keyspace with name 'foo' but 'bar.com_foo'. The client is not
aware of this and he still refers it
Could you supply some more information on how to reproduce this please. Such as
the schema, data inserted and the read command.

I'm having trouble understanding the steps you've described in step 1.
The error is raised because the Keyspace must exist in the system meta data.
It's used as the container to find the CF definition, and as part of the
Resource description when the request is Authorized .
Hope that helps.
Version: Cassandra 0.7.1
I am seeing following exception at regular interval (very frequently) in
Cassandra. I did a clean install of Cassandra 0.7.1 and deleted all old
data. Any idea what could be the cause? The stack is same for all the
occurrances.
Thanks,

ERROR [ReadStage:11232] 2011-
Hi Aaron,
Thank a lot for your help.
I have still some questions to get clarified.. The issue happens in the
following scenario.
1) Call add keyspace from a client API -The keyspace given by the client is
modified and used for further operations.
e.g Client's keysace = 'foo' and the his doma
Why wouldn't you leverage Lucandra/Solandra instead of starting
from scratch?

Under heavy load, this could be the result of the server not accept()ing
fast enough, causing the number of pending connections to exceed the listen
backlog size in the kernel.
I believe Cassandra uses the default of 50 backlogged connections.
This is one of the reasons why a persistent connectio
AFAIK The order of calling login() and set_keyspace() is not important. set_keyspace() just stores the keyspace in the ClientState on the connection thread, and login authenticates the user name and password and stores them in the ClientState. Functions on CassandraServer that require authorisatio
This issue came when I was trying to implement an idea listed at [

Hi All,
I observed the behavior indicated in the subject of this email even the
‘default User’ returned from authentication is null. Is this correct?

Am assuming these are client side side timeouts, you could increase the client
side timeout when the TSocket is created. Are you using a higher level library
or raw Thrift?.
Alternatively you may be overloading the cluster. Are there are WARN messages
in the cluster about Dropped Messages ?
Just to check whats going on...
You have a dead node 'A', it's turned off and still showing up in the nodetool
ring results for other nodes but the token field is empty. And you've tried
running nodetool removetoken on any other node in the cluster. Is that correct ?
Can you include the the out
There are two functions on the 0.7 API http://wiki.apache.org/cassandra/API to
count the columns in a row, get_count() and multiget_count() (not listed on the
wiki yet). Both of these will take a SlicePredicate which may have an empty
start and end.
The only way to count rows is to use get_ra
Robert,
Is this still an issue ?
What to the write latency attributes say for the CF's in JConsole ?
