-----------------------------------------------------------------

The current "solution" for this problem is to sleep for 1s if the prepare 
statement call fails with InvalidQueryException and retry this call. Using this 
fix the test program was able to terminate successfully creating the 500 
tables. This worked for all "reproduced in" server versions and for Java driver 
3.0.0 and 3.2.0.

Not sure what you want to do with this issue so I'll leave it open since this 
should have a proper solution.

This may eventually be used as a test scenario for CASSANDRA-10699

> Got "InvalidQueryException: unconfigured table" when preparing statement

>             Project: Cassandra
>          Issue Type: Bug
>         Environment: Host: Ubuntu 16.04.1 LTS, jdk 1.8.0_60-b27, docker 
> 1.11.2 and cassandra DataStax Java driver 3.0.0.
> The client program runs on the host and the cassandra cluster runs on docker 
> using the official docker cassandra image (multiple versions, see the 
> reproduced in field).
>            Reporter: João Silva
>         Attachments: cassandra_add_table.tar.gz
>
>
> I get the InvalidQueryException: unconfigured columnfamily (or table, 
> depending of the server version) when trying to prepare an insert statement 
> right after creating the table. This behavior is not deterministic but by 
> running the attached program the problem occurs almost always.
> First I start a 3 node cassandra cluster (RF=3) using the docker cassandra 
> image. Then a client Java program, using driver 3.0.0, starts 50 threads each 
> one creating 1 table (synchronously) and preparing an insert statement for it 
> (repeating this 10x for each thread). Eventually the exception occurs.
> *Important:*
> - I'm checking for schema agreement when creating the table and it seems to 
> be achieving it successfully. The schema agreement timeout was increased to 2 
> minutes.
> - This are *not* concurrent schema changes.
> Note that this is an extreme table creation test scenario to make the problem 
> more evident.
> See the README file in the attachment for instructions on how to start the 
> cluster and run the program.
