Can multiple Solr webapps access the same lucene index files?

[Mark Diggory <md...@gmail.com>]

Hello,

I have a question I can't find an answer to in the list.  Can mutliple solr
webapps (for instance in separate cluster nodes) share the same lucene index
files stored within a shared filesystem?  We do this with a custom Lucene
search application right now, I'm trying to switch to using solr and am
curious if we can use the same deployment strategy.

Yes, they could all point to an index that lives on a NAS or SAN, for example.  You'd still have to make sure only one server is writing to the index at a time.  Zookeeper can help with coordination of that.
