Cassandra does not update data using CQL using mutator

In the following code, I am trying to update a line

Keyspace fKeyspace = HFactory.createKeyspace(KEYSPACE, fCluster);

// Update with CQL
CqlQuery<String,String,String> cqlQuery =
   new CqlQuery<String,String,String>(fKeyspace, fStringS, fStringS, fStringS);
cqlQuery.setQuery(
    "INSERT INTO Fahrer (KEY, 'first') VALUES('fahrer1', 'FirstnameUpdated')");
QueryResult<CqlRows<String,String,String>> result = cqlQuery.execute();

// Update with mutator
Mutator<String> mutator = HFactory.createMutator(fKeyspace, fStringS);
MutationResult mr = mutator.insert("fahrer2", "Fahrer",
   HFactory.createStringColumn("first", "SecondUpdated"));

Updating the CQL query is not performed, the update is performed using the mutator. Where is the mistake?

It looks like your key and column name is transposed. For the keys, you have: "fahrer2" in the mutator and "first" in the CQL query.

If you have not already done so, for more information on CQL in Hector (and in general) see the following: https://github.com/rantav/hector/wiki/Using-CQL
