How to register Custom Data Type in Spark SQL UDF
0
I have class something like this
Class Test {
string name;
int age;
}
And My UDF method is:
public Test UDFMethod(string name, int age) {
Test ob = new Test();
ob.name = name;
ob.age = age;
}
Sample Spark query: Select *, UDFMethod(name, age) From SomeTable;
Now I want/need to register UDFMethod to execute above query in spark. Please help me on this.
