Spring Data & Cassandra CQL, can we create table that have a List of Map, then query it?

Im asking for the possibility to create a table in cassandra that contains a List of Map! like that:

CREATE TABLE IF NOT EXISTS agence(
id timeuuid,
code text,
libelle text,   
adresse set<frozen<map<text,text>>>,
conseillers  set<frozen<map<text,text>>>,
compagnie_id timeuuid,

...

In spring Data I have this query:

findAll()

then I got this error:

Query; CQL [SELECT * FROM agence;]; Codec not found for requested operation: [map<varchar, varchar> <-> java.util.Map]

I dont know if there is a bad configuration or bad use of cassandra!!

Anyone has suggestion please?

Finally I get a solution:

    /** The conseillers. */
@Column(value = "conseillers")
@Frozen
@FrozenKey
@FrozenValue
private Set<Map<String, String>> conseillers;

Like this we can map map <-> java.util.Map

    for(Row row : cassandraOperations.select("SELECT conseillers FROM agence", Row.class)){
        Set<Map<String, String>> info = mapperCassandra(row, "conseillers");
    }
}

private Set<Map<String, String>> mapperCassandra(Row row, String type) {
    return  row.getSet(type,    TypeTokens.mapOf(TypeToken.of(String.class), TypeToken.of(String
            .class)));

}
