Tim Vaillancourt commented on SOLR-4497:
----------------------------------------
What about the case where the alias already exists, but just has a new
destination (no alias miss)? Can/should the call return success on the change
reaching Zookeeper, or the running alias on all nodes? I'd prefer the later but
I expect that may be a significant amount of work.

> We should bring back the old aliasing feature, but for SolrCloud and with the
> ability to alias one collection to many.
> The old alias feature was of more limited use and had some problems, so we
> dropped it, but I think we can do this in a more useful way with SolrCloud,
> and at a level were it's not invasive to the CoreContainer.
> Initially, the search side will allowing mapping a single alias to multiple
> collections, but the index side will only support mapping a single alias to a
> single collection.
