One more update, it looks like the driver is generating this CQL statements:
SELECT
"test_id", "channel", "ts", "event", "groups" FROM "KEYSPACE"."test" WHERE
token("test_id") > ? AND token("test_id") <= ? ALLOW FILTERING;
Best regards,

Hi,
Probably this question has been already asked in the mailing list, but I
couldn't find it.
The question is how to measure disk-space used by a keyspace, column family
wise, excluding snapshots?

If you're looking to measure actual disk space, I'd use the du command,
assuming you're on a linux: http://linuxconfig.org/du-1-manual-page

Hi,
We're using Cassandra 2.0.8.39 through Datastax Enterprise 4.5.1 with a 9 nodes
cluster.
We need to add a few new nodes to the cluster but we're experiencing an issue
we don't know how to solve.
Here is exactly what we did :
- We had 8 nodes and need to add a few ones
- W

So OpsCenter doesn’t have to be the same size but it’s better if it’s at least
a c3 or m3 instance? Also, is it possible to set up a cluster with OpsCenter as
a different size using the Datastax AMI?
Thanks,

All,
I converted one of my C* programs to Hadoop 2.x and C* datastax drivers for
2.1.0. The original program (Hadoop 1.x) worked fine when we specified
InputCQLPageRowSize and InputSplitSize to reasonable values. For example, if we
had 60K rows, a row size of 100 and split size of 1 will

I don't have any thoughts on your specific issue at this time, but FWIW
#cassandra on freenode is sometimes a better forum for interactive
debugging of operational edge cases.

I was going through the WordCount example in the latest 2.1.7 Apache C*
source and there is a reference to
org.apache.cassandra.hadoop.cql3.CqlPagingInputFormat, but it is not in
the source tree or in the compiled binary. Looks like we really cannot use
C* with Hadoop without a paging input format.
Apologize, I meant version C* 2.0.16
The latest 2.1.7 source has a different WordCount example and this does
not use the CqlPagingInputFormat. I am comparing the differences to
understand why the change was made. But if you can shed some light on the
reasoning, it is much appreciated (and will save
