> I ran into this trying to add a Date type field to nifi-kudu-controller-service (https://issues.apache.org/jira/browse/NIFI-7551). The following code throws  _java.lang.IllegalArgumentException_ if _sql_date_ column is defined as DATE and _value_ is either _java.sql.Date_ or _int_
> {code:java}
> KuduPredicate.newComparisonPredicate(tableSchema.getColumn("sql_date"), KuduPredicate.ComparisonOp.EQUAL, value){code}
> If _value_ is DATE, _IllegalArgumentException_ is thrown by this code in KuduPredicate class:
> static long minIntValue(Type type) {
>   switch (type) {
>     case INT8:
>       return Byte.MIN_VALUE;
>     case INT16:
>       return Short.MIN_VALUE;
>     case INT32:
>       return Integer.MIN_VALUE;
>     case UNIXTIME_MICROS:
>     case INT64:
>       return Long.MIN_VALUE;
>     default:
>       throw new IllegalArgumentException("type must be an integer type");
>   }
> }
> if _value_ is an integer, then _IllegalArgumentException_ is thrown by this code
> {code:java}
> public static KuduPredicate newComparisonPredicate(ColumnSchema column,
>                                                    ComparisonOp op,
>                                                    long value) {
>   checkColumn(column, Type.INT8, Type.INT16, Type.INT32, Type.INT64, Type.UNIXTIME_MICROS,
>       Type.DATE);
> {code}
> as a result, if you have a table with DATE column, you cannot scan for it using the java client.
