Jonathan Coveney commented on PIG-1826:
---------------------------------------
MutableInt is defined as such:
package squeal.com;
public class MutableInt {
int value;
public MutableInt() { value = 1; }
public MutableInt(int val) { value = val; }
public void inc() { ++value; }
public void inc(int val) { value += val; }
public int get() { return value; }
public String toString() { return (new Integer(value)).toString(); }
}
Just a dumb wrapper class to avoid having to do another put after getting from
a Map.
it is failing on a trivial example:
1 a
1 b
1 c
2 a
2 b
2 c
3 a
3 b
3 c
