invalid version expected 2 but 10 or the data in not in 'javabin' formatI first saw it when I moved between versions of Solr, because versions 3+ use a different format. Most things I read were about this issue, and it was easy enough to resolve (I just made sure all my Solrs were on the same version - not so easy for everyone but worth the effort). But in one case I still had the error, and this whole javabin thing turned out to be a red herring. The answer (from here) is simply that the configuration of the slave included "admin" in the replication URL, which is not where the replication service itself exists. Doh! There was indeed something at the http://www.example.com/solr/admin/replication/ address, but it's the admin interface to replication rather than the endpoint itself, which was at http://www.example.com/solr/replication/. I'm not sure how the error crept in for me but clearly I'm not the only one! Perhaps I snipped it from some faulty documentation, but all those false positives going on about javabin format kept me busy trying all sorts of other things before I stumbled across the right answer. Anyway, check your solrconfig.xml on the slave to be sure your masterUrl string doesn't include "/admin" in the path.

Solr replication "invalid version" error
A quick one for googlers: I had this error in my catalina log when trying to replicate a Solr index:
