What do you see when you run "desc keyspace;” in cqlsh?

1 have downloaded cassandra 2.x and set up on single machine. Started
Cassandra server and connecting via cqlsh. Created a column family and
inserting a single record into it(via cqlsh).
Wondering why it gives "No node available"
Even though simple insert queries(without CAS) works!

If you are trying this out on a single node, make sure you set the
replication_factor of the keyspace to one.

Hello!
I got this error while trying out Cassandra 1.2.13. The error message looks
like:
Exception in thread "main" java.lang.
NoClassDefFoundError: org/apache/cassandra/service/CassandraDaemon
Caused by: java.lang.ClassNotFoundException:

Can you give the logs of both the machines. Logs will tell why it is taken
so long.
On a side note, you are using 2500 Cfs. I think you need to redesign this
schema.
Also 2 node cluster with RF=2, you might want to add a machine if it is
prod.

Hi,
We have a two node cluster with the replication factor of 2. The db has more
than 2500 column families(tables). The nodetool -pr repair on an empty
database(one or table has a litter data) takes about 30 hours to complete. We
are using Cassandra Version 2.0.4. Is there any way for
Hey Guys,
I’m new to CQL (but have been using C* for a while now). What would be the best

- A unique email address used for logging in

Certainly makes sense to not allow it. Any idea why the node would be holding
hints for tokens that don’t exist?

There are 3 other nodes that have a mild case. This is one node is worse by an
order of magnitude. deleteHintsForEndpoint fails with the same error on any of
the affected nodes.

Is this happening in one node or all. Did you try to delete the hints via
JMX in other nodes?

Also do you have any nodes down...because it is possible to reach write
consistency and not do CAS because some machines are down.

Hi ,
I’m hitting a very odd issue with HintedHandoff on 1 node in my 12 node cluster
running 1.2.13. Somehow it’s holding a large amount of hints for tokens that
have never been part of the cluster. Pretty sure this is causing a bunch of
memory pressure somehow that’s causing the node to go dow
What consistency level are you using?

I haven't actually tried to use that schema yet, it was just my first idea.
If we use that solution our app would have to read the whole table once a
day or so to find the top 5000'ish words.

Hi made some tests which succeed with all our operations (repair, add/remove
nodes ...). The only thing I'm worrying about is that I met a situation where I
had a lot of flushes on some nodes. You can find one of my system logs at
http://pastebin.com/YZKUQLXz. I'm not sure

i have a data model that creates a lot of tombstones (users home timeline
with many inserts and deletes). how can i reduce tombstones count it this
case?
>Is this all from cassandra ?
yes, with multithread compaction (for c3.4 - 6 threads),
compaction_through
Thanks.
Can I use sstableloader to load SSTables from a RandomPartitioner cluster
to a Murmuer3Partitioner cluster?
