In terms of the documentation, it would be great to augment the Table Configuration section of the user manual. Iterators are central to Accumulo's functionality so it would aid users to see an entire iterator life cycle:
- Develop iterator by extending...
- Install iterator as jar to lib/ext
- Run as in a client (fragment is shown)
- Set via shell (setiter, config for options)
There are hints to using config for existing filters but not how to configure custom iterator code. For example, installing custom iterator code for non-scan contexts is unclear.
