Yonik Seeley commented on SOLR-4905:
------------------------------------
You can do a cross-core join on any two cores in the same node (JVM).
Join does not (yet) have cross-node support, and doing so would always be an
order of magnitude slower in any case.
> Cross core joins don't work for SolrCloud collections and/or aliases

> Key: SOLR-4905
> URL: https://issues.apache.org/jira/browse/SOLR-4905
> Project: Solr
> Issue Type: Bug
> Components: SolrCloud
> Affects Versions: 4.2
> Reporter: Philip K. Warren
>
> 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.
