Thanks, setters and getters for public fields have no purpose. Also per the
conditions you have mentioned:
"All fields either have to be public or there must be getters and setters for
all non-public fields.”
Since my fields are declared public there are no impact on adding getters and
setters. ( I have also testing after adding the setters and getters and as
expected that has no effect).
Could you spot anything else? this should be really easy basic case. I am
really wondering why it is not working.
For the people who are lazy to open the gist code snippet, this is what I am
trying to do:
pojoExampleDataStream.
keyBy("productId").
sum("count").
print();

You don't have getters and setters for count and productId.
Your class should be
public class PojoExample {
public int count;
public String productId;
public PojoExample() {}
public int getCount() {
return count;
}
public void setCount(int count) {
this.count = count;
}
public String getProductId() {
return productId;
}
public void setProductId(String productId) {
this.productId = productId;
}
}

Thanks Flavio, but as you can see in my code I have already declared my pojo to
achieve those conditions:
public class PojoExample {
public int count;
public String productId;
public PojoExample() {
}
}
So it cannot be that.

Conditions for a class to be treated as a POJO by Flink:
* The class must be public
* It must have a public constructor without arguments
* All fields either have to be public or there must be getters and setters
for all non-public fields. If the field name is foo the getter and setters must
be called getFoo() and setFoo().
I don't know whether you need to implement also hashCode() and equals() actually

Hi,
I was trying to test some specific issue, but now I cannot seem to get the very
basic case working. It is most likely that I am blind to something, would
anyone have quick look at it?

It is just a collection of pojos where I am just trying to keyBy one field and
sum into the other, but I am getting:
5> PojoExample{count=0, productId='productA'}
8> PojoExample{count=0, productId='productB'}
5> PojoExample{count=0, productId='productA'}
8> PojoExample{count=0, productId='productB'}
5> PojoExample{count=0, productId='productA'}
5> PojoExample{count=0, productId='productA'}
5> PojoExample{count=0, productId='productA’}
