Hi Madhvi,

It's likely going to be much easier for you to add to Lucene in such a 
way that you can just write to and query Accumulo tables rather than 
trying to create files that Accumulo can use as a first step.

I'm not familiar enough with Lucene to tell you where to look in their 
codebase for extension points. Without knowing what interfaces you would 
need to implement for Lucene, it's hard to suggest examples of table 
structures that you would need to create. Sorry that's not more helpful. 
Perhaps someone else is more familiar with this.
