> CQLSSTableWriter throws Exception when trying to use Update statement.
> Has been working fine in previous versions for me.

> 		final String TABLE = "data";
> 		final String schema = "CREATE TABLE " + KS + "." + TABLE

> 		final String query = "UPDATE " + KS + "." + TABLE + " SET v = ? WHERE k = ? and c1
= ? and c2 = ? and c3 = ?";
> 		File dataDir = new File(...);
> 		CQLSSTableWriter writer = CQLSSTableWriter.builder().inDirectory(dataDir).forTable(schema).using(query).build();
//Exception here (see below) 
> 		HashMap<String, Object> row = new HashMap<>();
> 		row.put("k", "a");
> 		row.put("c1", "a");
> 		row.put("c2", "a");
> 		row.put("c3", "a");
> 		row.put("v", "v");
> 		writer.addRow(row);
> 		writer.close();

> I'm currently testing it with 3.7 version, my POM looks like this:

>   <groupId>com.datastax.cassandra</groupId>
>   <artifactId>cassandra-driver-core</artifactId>
>   <version>3.0.0</version>
> </dependency>
> {code}
> It has been working with 3.0.8 versions in the POM, but that version is somehow not including
the UDT support? 
> I want to use UPDATE instead of INSERT because I need to append data to lists and do
not want to overwrite existing data in the lists.
