Jonathan Ellis commented on CASSANDRA-4707:
-------------------------------------------
I don't see how this ties into schema changes. Here's CFSerializer.deserialize:
{code}
public ColumnFamily deserialize(DataInput dis, IColumnSerializer.Flag flag,
ISortedColumns.Factory factory) throws IOException
{
if (!dis.readBoolean())
return null;
// create a ColumnFamily based on the cf id
int cfId = dis.readInt();
if (Schema.instance.getCF(cfId) == null)
throw new UnknownColumnFamilyException("Couldn't find cfId=" +
cfId, cfId);
ColumnFamily cf = ColumnFamily.create(cfId, factory);
deserializeFromSSTableNoColumns(cf, dis);
deserializeColumns(dis, cf, flag);
return cf;
}
{code}
So:
# serialization relies on the cfId, not cfname, so creating a new cf with the
old name should have no effect (the new cf will get a different id)
# if the cf is dropped, it won't be in the Schema map anymore and
UnknownColumnFamilyException should be thrown (which HHOM handles)
If you can give steps to reproduce that would help a lot.
