[jira] [Updated] (SOLR-4905) Allow fromIndex parameter to JoinQParserPlugin to refer to a single-sharded collection that has a replica on all nodes

     [ https://issues.apache.org/jira/browse/SOLR-4905?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Timothy Potter updated SOLR-4905:
---------------------------------
    Summary: Allow fromIndex parameter to JoinQParserPlugin to refer to a single-sharded collection that has a replica on all nodes  (was: Cross core joins don't work for SolrCloud collections and/or aliases)

Renaming this ticket to be more clear about the solution it is solving.

> Using a non-SolrCloud setup, it is possible to perform cross core joins (http://wiki.apache.org/solr/Join). When testing with SolrCloud, however, neither the collection name, alias name (we have created aliases to SolrCloud collections), or the automatically generated core name (i.e. <collection>_shard1_replica1) work as the fromIndex parameter for a cross-core join.
