Well, that's perfect!  Lucene's IW.updateDoc is atomic per row/doc.
As a row is added to HBase, we'd add/update a doc in Lucene.  Part of
the integration would entail keeping enough of the HBase
write-ahead-Log (WAL) intact, so that if a region server failed, the
Lucene index that was still in RAM could be rebuilt on startup.
