Accumulo Iterators really aren't designed to support writes from within
Accumulo itself. Deadlock within Accumulo and lack of lifecycle methods
are the two big problems. Iterators really weren't designed for this
purpose.
Fluo[1] (formerly known as Accismus), an implementation of Percolator
using Accumulo, is really the "correct" tool to target for incremental
updates for documents.

Is there a way to tie into the write process in Accumulo? Maybe just use an
Iterator that worked on compaction to send data to blur/solr? I have seen
something similar in Cassandra, a data hook to save data in Solr.

We were trying to do so, but adding visibility while adding/searching
documents needs lot more thinking. Adding visibility to core search engine
needs changes to algorithm and that does not make it very scalable.
Integration besides granular visibility is very doable. and we had taken
inspiration from Solandra.
Obviously if we can get it done it adds lot of value. I believe Sqrrl
people have already done it, are they thinking to open source it anytime in
future?

We briefly toyed with blur on accumulo but didnt get too far just because
it was obe. I think that would be cool.

It's definitely possible. I remember hearing about someone doing lucene
on top of Accumulo once, but I don't recall seeing a nice package with a
bow on top.

What lexical search package (like lucene/solr) has anyone put on top
of
accumulo? Is this possible or does everyone just index log files and
documents?
