-------------------------------------------
Summary: Avoid sending the shard.url parameter in shard requests
Key: SOLR-9378
URL: https://issues.apache.org/jira/browse/SOLR-9378
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Components: search, SolrCloud
Reporter: Shalin Shekhar Mangar
Priority: Minor
Fix For: 6.2, master (7.0)
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.
