Per http://www.datastax.com/docs/datastax_enterprise3.0/solutions/dse_search_cluster one cannot run a DSE cluster containing both regular Cassandra nodes and Solr search nodes in the same data center. Why is this?
We are looking at using Solr to provide full-text search capability for data that we're storing in Cassandra. We have multiple physical data centers, but we obviously want to have both Solr nodes and Cassandra nodes in each data center for redundancy and scalability.
