So after implementing deepCopy() (below) and calling it during init(), I still
receive the same error
@Override
public SortedKeyValueIterator<Key,Value> deepCopy(IteratorEnvironment
env)
{
System.out.println(String.format("%s.deepCopy() called",
getClass().getName()));
return super.deepCopy(env);
}
Is this implementation correct or am I missing something fundamental?
Thanks,
Mike G.

Hey Michael, I ran into something similar when I didn't implement the
deepcopy() method on my custom iterator. Inside the deepCopy method you will
need to make sure you copy any options your iterator implements.

Given this code :

IteratorSetting iterSetting = new IteratorSetting(10, "filterName",

iterSetting.addOption("option1", "value1");
iterSetting.addOption("option2", "value2");
scanner.addScanIterator(iterSetting);
Iterator<Entry<Key,Value>> iter = scanner.iterator();
iter.hasNext();
I am receiving this exception when hasNext() is called :

If anyone can shed light on what I am doing wrong, I would deeply appreciate it.
