[1.1] Can't create column
[default@ks] create column family Post with column_type = 'Standard' and
column_metadata = [{column_name: 'user', validation_class: 'UTF8Type'},
{column_name: 'type', validation_class: 'UTF8Type'}] and comment = 'bla';
java.lang.RuntimeException:
org.apache.cassandra.db.marshal.MarshalException: cannot parse 'user' as
hex bytes

Yes, it's the comparator, not the single quotes. The column_name in
the column_metada is, as the name imply, a column name. Thus is must
be compatible with the column family comparator. The default
comparator of a column family is BytesType, which interpret it's value
has hex string representing bytes and thus you get the error that
"user" is not a hexadecimal string. So you have to specifiy a
comparator that specifically handle strings, like UTF8Type or
AsciiType.

It's the comparator so? because I tried without the single quotes on
column_name and same error
