Jonathan Ellis commented on CASSANDRA-4093:
-------------------------------------------

bq. I'm not sure how many people use composite comparators and have 
ColumnDefinition on them, but we probably shouldn't assume nobody does that

given that you can't do that with the cli (as shown here) I think that's 
actually a pretty safe assumption.

> ColumnDefinition.{ascii, utf8, bool, ...} static methods used to initialize 
> schema_* CFs column_metadata do not respect CF comparator and use 
> ByteBufferUtil.bytes(...) for column names which creates problems in CLI and 
> probably in other places.
> The CompositeType validator throws exception on first column
> String columnName = columnNameValidator.getString(columnDef.name);
> Because it appears the composite type length header is wrong (25455)
