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.
