used Hector before and would like to evaluate astynax. Not sure, how it is
accepted in Cassandra community. Any issues with it or advantagest? API
looks very clean and simple compare to Hector. Has anyone used it in
Thank you all for the responses to this thread. I am planning to use
Cassandra 1.1.9 with Astynax. Does anyone has Cassandra 1.x version running
in production with astynax? Did you come across any show-stopper issues?
Thanks

I am trying to understand multi DC setup for cassandra. As I understand, in
this setup, replicas exists in same cluster ring, but physically nodes are
distributed across DCs. Is this correct?
I have two different cluster rings in two DCs, and want to replicate data
bidirectionally. They both have
to endure split-brain
for a while.

I'm using spark 1.5.1 version. I am reading data from Kafka into Spark
and writing it into Cassandra after processing it. Spark job starts
fine and runs all good for some time until I start getting below

I would appreciate any clue on this. It has become a bottleneck for our
spark job.

Hi,
Has anyone tried accessing Cassandra data using SparkShell? How do you do
it? Can you use HiveContext for Cassandra data? I'm using community version
of Cassandra-3.0
Thanks,

Hi,
I am using spark 1.6. I wrote a custom receiver to read from WebSocket. But
when I start my spark job, it connects to the WebSocket but doesn't get
any message. Same code, if I write as separate scala class, it works and
prints messages from WebSocket. Is anything missing in my Spark Code?
