My steps to reproduce (Сassandra 2.0.9):
# In one node datacenter DC1 create a keyspace with NetworkTopologyStrategy,
options DC1=1, DC2=1.
# Create a CF with a secondary index on a CompositeType(Int32Type, UUIDType).
# Write any composite value to a row.
# Drop the value.
# Write another composite value to another row.
# Drop second value.
# Bootstrap add a new node in DC2.
# DC2 gets an exception.
The similar issue I got on indexed composite column in a single 3 nodes DC
with SimpleStrategy and replication_factor=3 (cassandra 1.2.18).
I use Astyanax 2.0.1 (I tested on Astyanax 1.56.49 as well), here is the code
that generates keyspace that fails to bootstrap on a new node:

> My steps to reproduce (Сassandra 2.0.9):
> # In one node datacenter DC1 create a keyspace with NetworkTopologyStrategy,
> options DC1=1, DC2=1.
> # Create a CF with a secondary index on a CompositeType(Int32Type, UUIDType).
> # Write any composite value to a row.
> # Drop the value.
> # Write another composite value to another row.
> # Drop second value.
> # Bootstrap add a new node in DC2.
> # DC2 gets an exception.
> The similar issue I got on indexed composite column in a single 3 nodes DC
> with SimpleStrategy and replication_factor=3 (cassandra 1.2.18).
> I use Astyanax 2.0.1 (I tested on Astyanax 1.56.49 as well), here is the code
> that generates keyspace that fails to bootstrap on a new node:
