Mark Miller reassigned SOLR-4321:
---------------------------------
Assignee: Mark Miller
> SolrCloud collection CREATE will put multiple master shards on a single node
> (and no shards on some)
> ----------------------------------------------------------------------------------------------------
>
> Key: SOLR-4321
> URL: https://issues.apache.org/jira/browse/SOLR-4321
> Project: Solr
> Issue Type: Bug
> Components: SolrCloud
> Affects Versions: 4.1
> Reporter: Brett Hoerner
> Assignee: Mark Miller
> Attachments: SOLR-4321.patch, SOLR-4321.patch
>
>
> This is best described by a photo of my SolrCloud admin:
> http://i.imgur.com/hW4xnxy.png
> I have a 4 node cluster, with shard count of 2 and replication factor of 2.
> After running something like,
>
> http://localhost:8983/solr/admin/collections?action=CREATE&name=15724&numShards=2&replicationFactor=2
> The shards seem to be completely randomly placed, which is fine, but some
> nodes receive more of the share than others (some even receiving none).
> For example, 15724 has given node "backfill-1d" 2 "parts",
> 15724_shard1_replica2 and 15724_shard2_replica1 but has given "backfill-2d"
> nothing at all.
> This creates unnecessary load on some nodes, no? Is this something I am
> supposed to handle myself (I looked, but don't see how).
