Erick Erickson commented on SOLR-10974: --------------------------------------- Please raise this question on the user's list at solr-u...@lucene.apache.org, see: (http://lucene.apache.org/solr/community.html#mailing-lists-irc) there are a _lot_ more people watching that list who may be able to help. If it's determined that this is a code issue in Solr and not a configuration/usage problem, we can raise a JIRA. As it stands, there is very little information to go on here. Exactly _how_ did you "activate the replication of a shard via the web interface,"? > Replication - Unable to download tlog > ------------------------------------- > > Key: SOLR-10974 > URL: https://issues.apache.org/jira/browse/SOLR-10974 > Project: Solr > Issue Type: Bug > Security Level: Public(Default Security Level.
