multiple threads updating result in TransportException
We're running into a problem where things are fine if our client runs
single threaded but gets TransportException if we use multiple threads.
The datastax driver gets an NIO checkBounds error.
Here is a link to a stack overflow question we found that describes the
problem we're seeing. This question was asked 7 months ago and got no
answers.
We're running C* 2.0.9 and see the problem on our single node test cluster.
Here is the stack trace we see:

Re: multiple threads updating result in TransportException
Posted by Eric Stevens <mi...@gmail.com>.
A lot of people do a lot of multi-threaded work with Datastax Java Driver.
It looks like you're using Cassandra Driver 2.0.0-RC2, might I suggest as a
first step, at least upgrade to 2.0.0 final? RC2 wasn't even the final
release candidate for 2.0.0.
