> When running multiple simultaneous instances of the test_cql.py piece of the
> python-cql test suite, I can reliably reproduce intermittent and
> unpredictable errors in the tests.
> The failures often occur at the point of keyspace creation during test setup,
> with a CQL statement of the form:
> {code}
> CREATE KEYSPACE 'asnvzpot' WITH strategy_class = SimpleStrategy
> AND strategy_options:replication_factor = 1
>
> {code}
> An InvalidRequestException is returned to the cql driver, which re-raises it
> as a cql.ProgrammingError. The message:
> {code}
> ProgrammingError: Bad Request: line 2:24 no viable alternative at input
> 'asnvzpot'
> {code}
> In a few cases, Cassandra threw an ArrayIndexOutOfBoundsException and this
> traceback, closing the thrift connection:
> {code}
> ERROR [Thrift:244] 2012-02-10 15:51:46,815 CustomTThreadPoolServer.java (line
> 205) Error occurred during processing of message.
