Hi, I just migrated to solr 3.3 from 1.4.1. My index is still in 1.4.1 format (will be migrated soon).
I have an error when I use sharding with the new version: org.apache.solr.common.SolrException: java.lang.RuntimeException: Invalid version (expected 2, but 1) or the data in not in 'javabin' format However, if I request each shard independently (/request), answer is correct. So the error is triggered only with the shard mechanism. While I foresee to upgrade my indexes, I'd like to understand the issue, e.g. is it an "upgrade" issue or don't shards support using an "old" format. Thanks Olivier
