Vaibhav Thapliyal commented on ACCUMULO-3633:
---------------------------------------------

Thank you everyone for replying specially Josh for releasing a patch for the documentation.
It would be great Josh if you could put together some code as to how the tabletserver calls
the Iterator as it might be helpful. Thanks, you all are awesome.

> Dear all,
> Can you please provide a documentation regarding creating custom Iterators. For example,
explain the functionality  of the functions inside SortedKeyValueIterator and how to override
those functions.
> Please explain how these functions are executed (which class calls these functions when
the iterator executes).
> I would appreciate if these changes are made in your future documentations as this would
help developers who are new to accumulo to quickly get started on writing their own custom
iterators which is an essential part of accumulo.
