Hi Gopal,

Indeed, for a single Lucene index, only one writer may be open at a time.
Lucene tries to catch you if you mess this up, using file-based locking.

If you really need concurrent indexing, you could have N IndexWriters each
writing into a private Directory, and then periodically use addIndexes to
"reduce" these indices down into a single index which you then use for
searching.

Zookeeper, right? Look how Zookeeper is used in Solr, but Zookeeper does exactly what you want, I believe.
