Billie Rinaldi commented on ACCUMULO-700:
-----------------------------------------

If we configure iterators using, say, comma-separated base64-encoded 
representations of IteratorSettings, a potential disadvantage is that the 
iterator information will no longer be readable in the job configuration.  Does 
anyone need this to remain readable?

> The InputFormatBase currently uses AccumuloIterator and 
> AccumuloIteratorOption configuration objects to serialize iterator 
> information for MapReduce.  These objects predate IteratorSetting, which is 
> now used to configure iterators.  We should just make IteratorSetting 
> Writable so it can be used directly for serializing iterator information.
