Similar tests with Spark and cassandra connector (which uses the native driver
too) work well ... I was wondering if Yarn was restricting the network access
but even executing spark (using spark-shell) with --master yarn-client or
--master yarn-server worked without any issue. You could also see
That's a pretty basic error from the driver. I would look at the target
node and make sure that the IP/port combination is actually bound and free
of any firewall shenanigans.

Hi,
Trying to execute an Hadoop job on Yarn, I got errors from Cassandra's internal
code. It seems that connections are closed but I can't understand why ...
Here is a subtract of the errors :
