>             Project: Apache Cassandra
>          Issue Type: Bug
>            Reporter: Jon Haddad
>            Priority: Normal
>
> The scenario:
> New DC is added
> Data is replicated to new DC for keyspace "mykeyspace" via a rebuild
> DC is dropped in replication
> DC is re-added to "mykeyspace"
> When this happens, the user is unable to rebuild as available_ranges_v2 thinks it's unnecessary.  
> We should remove mykeyspace from system.available_ranges_v2 when removing a DC.
> Found in 4.1
