> If argTypes[0] is Array<Double> ,it will throw exception.

> {code:java}
> Caused by: org.apache.flink.table.functions.hive.FlinkHiveUDFException: Flink doesn't support primitive array for Hive functions yet.
> at org.apache.flink.table.functions.hive.util.HiveFunctionUtil.isSingleBoxedArray(HiveFunctionUtil.java:34) {code}

> I think we should determine whether the argTypes is Array , replace primitive Array type.`
> If argsType is Array , inputs should be converted to an object[].
> If argsType is not Array, we can keep origin code logic.
> HiveFunctionUtil.isSingleBoxedArray(argTypes); throws exception when argTypes is Array and the element type is BOOLEAN | TINYINT | SMALLINT | INTEGER | BIGINT | FLOAT | DOUBLE.
> Correct me if I am wrong， thanks
