Subject Need help - How to use Custom java object in Hive UDAF
Date Wed, 29 Oct 2014 13:13:38 GMT

Hi Team,

I am working on a hive - UDAF function in which I need to return a custom java object. Please
let me know how can I implement this.
Also please let me know if any additional information required.

Return object :-

MAP < <Text> , <Custom Java Object : Child>  >

Custom Java Object :-

class Child {
private Text chldName;
             private Text mgrName;
             private Text chldId;
             private ArrayList<Child> reportees = new ArrayList<Child>();

             Child(Text id, Text name) {
                    this.chldId = id;
                    this.chldName = name;

             public void setChldName(Text chldName) {
                    this.chldName = chldName;

             void add(Child chld) {
                    if (chld != null && !reportees.contains(chld)) {

             public ArrayList<Child> getReportees() {
                    return reportees;
