If you create a table via CQL, then insert into it (via Java API) with an incorrect number of components. The insert works, but select * from CQL results in a TSocket read error. I showed this in the webinar last week, just in case people ran into it. It would be great to translate the ArrayIndexOutofBoundsException from the server side into something meaningful in cqlsh to help people diagnose the problem. (a regular user probably doesn't have access to the server-side logs) You can see it at minute 41 in the video from the webinar: http://www.youtube.com/watch?v=AdfugJxfd0o&feature=youtu.be -brian On Tue, Oct 9, 2012 at 9:39 AM, Jonathan Ellis <jbel...@gmail.com> wrote: > Sounds like you're running into the keyspace drop bug.
