> Environment: OS: Windows 7,
> Server: Cassandra 1.1.9 release drop
> Client: astyanax 1.56.21,
> JVM: Sun/Oracle JVM 64 bit (jdk1.6.0_27)

> Attached is a driver that sequentially:
> 1. Drops keyspace
> 2. Creates keyspace
> 4. Creates 2 column families
> 5. Seeds 1M rows with 100 columns
> 6. Queries these 2 column families
> The above steps are repeated 1000 times.
> The following exception is observed at random (race - SEDA?):
> ERROR [ReadStage:55] 2013-01-29 19:24:52,676 AbstractCassandraDaemon.java

> This exception appears in the server at the time of client submitting a query
> request (row slice) and not at the time data is seeded. The client times out
> and this data can no longer be queried as the same exception would always
> occur from there on.
> Also on iteration 201, it appears that dropping column families failed and as
> a result their recreation failed with unique column family name violation
> (see exception below). Note that the data files are actually gone, so it
> appears that the server runtime responsible for creating column family was
> out of sync with the piece that dropped them:
