Well, then you could trying
run any streaming process (repairs / bootstrap / node removal) during the
upgrade and while you have not yet run "nodetool upgradesstable". There is a
lot of informations out there about upgrades.

Subject: nodetool drain running for day
The fact that there is one single DC does not mean that you do not need
multiples nodes. Without multiples nodes you do not have redundancy (the nodes
fail and you lose the database) and you cannot scale the cluster if the number
of users and/or rows grows adding more nodes unless you have test
When we start using cassandra in our company, we decide to use a single node
Cassandra cluster as PoC. Everything was correct until we really need the power
of a Cassandra cluster and then our data models were not appropriate for a
cluster with multiple nodes because of redundancy, data access p
We are having performance problems with our cluster regarding to timeouts when
repairs are running or massive deletes. One of the advice I received was update
our casssandra version from 2.0.17 to 2.2. I am draining one of the nodes to
start the upgrade and the drain is running now for two days.

Hi everyone
We are having problems with our cluster (7 nodes version 2.0.17) when running
"massive deletes" on one of the nodes (via cql command line). At the beginning
everything is fine, but after a while we start getting constant

Hi
Our opscenter can not connect to the nodes, in the logs the next error appears:

Hi
At the end, we have solved the problem deleting also the Opscenter keyspace
from the cluster and restarting the opscenter. Then the retry attemps to the
old nodes in the cluster disappeared.

Hi
We were having some issues with different versions in our cluster and the info
which appear in Opscenter. We decide to delete the datastax-agents in each of
the nodes and delete the cluster from the opscenter.
But I still see on the opscenter logs attemps to retry connections to the nodes

Hi Kevin
We are using a similar solution than horschi. In the past we use CassandraUnit
(https://github.com/jsevellec/cassandra-unit) but truncate the tables after and
before each test works better for us. We also set gc_grace_seconds to zero.

Hi tsi
We faced a similar situation a few months ago. At the end what we make is
developed a service in our application to migrate the data from the old
cassandra 1.2 to the new cassandra 2.0 using cql (with normal SELECT and UPDATE
commands) (our application at that moment have two cassandra s
Hi Mikhail
It is not a bug/not implemented feature and you are not doing nothing wrong.
As you can check on the documentation you can only filter on a key name or a
column that has a secondary index created on it:

Hi
To manage the cluster we are using the OpsCenter, it is a free web tool from
Datastax that allow you basic execute basic operations in any node on the
cluster. It also contain differents metrics which you can add to a kind of
dashboard and monitoring the most important parameters in the clus
