So some of my non-live tables are back live again, and obviously some of
the big ones!!

Anton,
I have also seen this issue with decommissioned nodes remaining in the
system.peers table.
On the bright side, they can be safely removed from the system.peers table
without issue. You will have to check every node in the cluster since this
is a local setting per node.

Hi,
I have a keyspace which is using about 19GB on most nodes in the cluster.
However on one node the data directory for the only table in that keyspace
now uses 52GB. It seems that old sstables are not removed after compaction.
Here is a view of the data directory Data files before compaction
Restarting this node removed the decommissioned node from gossip.

the trick was to add -Dcassandra.load_ring_state=false somehow to the jvm
parameters
I'm not sure if it works for 2.0 (since it's not in the doc for 2.x)

only read when cassandra starts but updating the seed list to live nodes
and then doing a roiling restart fixed this issue for me.
I hope this helps you.
Thanks

Hi,
I have a cluster which had 4 datacenters running 2.0.12. Last week one of
the datacenters was decommissioned using nodetool decommission on each of
the servers in turn. This seemed to work fine until one of the nodes
started appearing in the logs of all of the remaining servers with messages
Hi,
It doesn't look like this is possible, but can I select all rows missing a
certain column? The equivalent of select * where col is null in SQL.

You should be able to get most of this information from the datastax
documentation, e.g. http://www.datastax.com/docs/1.0/references/cql/index for
version 1.0.

First, note that replication is done at the row level, not at the node level.
That line should look more like:
placement_strategy = 'NetworkTopologyStrategy' and strategy_options = {DC1:
1,DC2: 1,DC3: 1 }
This means that each row will have one copy in each DC and within each DC it's

Good to see I'm not alone in this! I just set up a fresh test cluster. I first
did a fresh install of 1.1.0 and was able to replicate the issue. I then did a
fresh install using 1.0.10 and didn't see the issue. So it looks like rolling
back to 1.0.10 could be the answer for now.

definitively a bug and it's be easier to follow up there.
Did you try restarting the node on which you try the create keyspace?

Hi,
I'm doing testing and wanted to drop a keyspace (with a column family) to
re-add it with a different strategy. So I ran in cqlsh:
DROP KEYSPACE PlayLog;
CREATE KEYSPACE PlayLog WITH strategy_class = 'SimpleStrategy'
AND strategy_options:replication_factor = 2;
And everything seemed to

As a follow up, I am running version 1.1 and have tried nodetool repair,
cleanup, compact. I can create other keyspaces, but still can't create a
keyspace called PlayLog even though it is not listed anywhere.

Hi,
I am looking at cassandra for a logging application. We currently log to a
Postgresql database.
I set up 2 cassandra servers for testing. I did a benchmark where I had 100
hashes representing logs entries, read from a json file. I then looped over
these to do 10,000 log inserts. I

Writing serially over one connection will be slower. If you run many threads
hitting the server at once you will see throughput improve.
