Thank you Paul and Erick. The keyspace is defined like this:
CREATE KEYSPACE doc WITH replication = {'class': 'SimpleStrategy',
'replication_factor': '3'}Â AND durable_writes = true;
Would that cause this?
The program that is having the problem selects data, calculates stuff,
and inserts. It works with smaller selects, but when the number of
rows is in the millions, I start to get this error. Since it works with
smaller sets, I don't believe it to be a network error. All the nodes
are definitely up as other processes are working OK, it's just this one
program that fails.
The full stack trace:
Error: com.datastax.oss.driver.api.core.NoNodeAvailableException: No
node was available to execute the query

Hi Joe
This could also be caused by the replication factor of the keyspace,
if you have NetworkTopologyStrategy and it doesn’t list a
replication factor for the datacenter datacenter1 then you will get
this error message too.Â

Does it get returned by the driver every single time? The
NoNodeAvailableExceptiongets thrown when (1) all nodes are down, or
(2) all the contact points are invalid from the driver's perspective.
Is it possible there's no route/connectivity from your app server(s)
to the 172.16.x.xnetwork? If you post the full error message + full
stacktrace, it might provide clues. Cheers!
