Shalin Shekhar Mangar commented on SOLR-6917:
---------------------------------------------
bq. I'm not sure we should do this. The most common usecase is that somebody
just gave a wrong name and it is genuinely not there. It actually does all this
work for all requests.
Sorry, I incorrectly described the change. Look at the patch that I posted for
details. It doesn't actually make requests to all the shards but only tries to
select an active replica looking at all shards.
But now that you raised this question, this logic of selecting a shard is
itself wrong -- the jar will be in exactly one shard and we should find the
right shard and go to it directly. This indirection isn't saving us anything
except when numShards=1.
