> The shard.url parameter contains a list of all replicas for a shard. One of those is chosen by the HttpShardHandler to execute the request. So, it is used only within the context of processing request on a distributor node as a special storage for a list of replicas urls between the prep and execution phase of HttpShardHandler. There is no real need to send this parameter down to the chosen shard.
> However, Hoss pointed out to me that removing this would break ShardAugmenterFactory so we need to figure out if/how we can do this. Personally, I don't think it is at all useful to write down *all* replicas with the document without telling which replica really served the query.
