Hey folks, I'm getting SolrServerExceptions and I'm not sure whether this is by design or whether this is a concurrency bug of some sort.
Basically I've got a pretty active collection which is being queried all the time. Periodically, new shards are created (using the Collection Admin API's CREATESHARD call). Creating the shard takes a certain amount of time. If a query is launched during the shard creation, I get a SolrServerException from SolrJ: Error from server at foo: no servers hosting shard: bar This strikes me as odd. It's a new shard that's either still being created or was just created, it's empty, so it shouldn't affect the query in any way. I had a quick nose around the code and found HttpShardHandler to be the one throwing the exception. But it's unclear to me how or where it's decided which shards are included in the query execution. Is this a bug? Thanks, - Bram
