Datastax Java Driver vs Cassandra 2.1.7
Hi,
I’m using Datastax Java Driver V 2.1.6
I migrated my cluster to Cassandra V2.1.7
And now I have an error on my client that goes like:
2015-06-23 10:49:11.914 WARN 20955 --- [ I/O worker #14] com.datastax.driver.core.RequestHandler : /192.168.2.201:9042 replied with server error (java.lang.AssertionError), trying next host.
And on the node I have an NPE

I agree. Thanks a lot.

I went to see the query that I used since many months… which was working…. but obviously there is something wrong with it.
The problem with it was *simply* that I placed twice the same field in the select. I corrected in my code and now I don’t have the error with 2.1.7.
This provocated the error on the nodes:

I can also reproduce the error on cqlsh:

Hi Sam,
You have a real good gut feeling.
I went to see the query that I used since many months… which was working…. but obviously there is something wrong with it.
The problem with it was *simply* that I placed twice the same field in the select. I corrected in my code and now I don’t have the error with 2.1.7.
This provocated the error on the nodes:

Can you share the query that you're executing when you see the error and
the schema of the target table? It could be something related to
CASSANDRA-9532.
