> There are 2 bugs in the method
> {code}
> addRow(Map<String, Object> values)
> {code}
> First issue is that the map <b>must</b> contain all the column names as keys in the map otherwise the addRow fails (with InvalidRequestException "Invalid number of arguments, expecting %d values but got %d").
> Second Issue is that the keys in the map must be in lower-case otherwise they may not be found in the map, which will result in a NPE during decompose.
> h6. SUGGESTED SOLUTION:
> Fix the addRow method with:
> {code}
> public CQLSSTableWriter addRow(Map<String, Object> values)
>     throws InvalidRequestException, IOException
> {
>     int size = boundNames.size();
>     Map<String, ByteBuffer> rawValues = new HashMap<>(size);
>     for (int i = 0; i < size; i++) {
>         ColumnSpecification spec = boundNames.get(i);
>         String colName = spec.name.toString();
>         rawValues.put(colName, values.get(colName) == null ? null : ((AbstractType)spec.type).decompose(values.get(colName)));
>     }
>     return rawAddRow(rawValues);
> }
> {code}
> When creating the new Map for the insert we need to go over all columns and apply null to missing columns.
> Fix the method documentation add this line:
> {code}
>      * <p>
>      * Keys in the map <b>must</b> be in lower case, otherwise their value will be null.
>      *
> {code}
