I know there was some effort to fix this but I must report that solr 4.2.1 has still problems with index version and index generation numbering in master/slave mode with replication.
Test was: 1. installed solr 4.2.1 on master and build index from scratch 2. installed solr 4.2.1 on slave with empty index 3. replicated master to slave, everything was fine, both in sync 4. deleted index on master with *:* and build index from scratch 5. replicated index from master to slave RESULT: slave has different (higher) version number and is with generation 1 ahead :-( Regards Bernd
