Hi, Deduplication on SolrCloud through the SignatureUpdateRequestProcessor is not functional anymore. The problem is that documents are passed multiple times through the URP and the digest field is added as if it is an multi valued field. If the field is not multi valued you'll get this typical error. Changing the order or URP's in the chain does not solve the problem.
Any hints on how to resolve the issue? Is this a problem in the SignatureUpdateRequestProcessor and does it need to be updated to work with SolrCloud? Thanks, Markus
