Gus Heck commented on SOLR-13142:
---------------------------------
Jira is not a support portal, so normally if you feel like writing "can anyone
provide help" you've landed in the wrong place (and ignored the BRIGHT RED text
on the issue creation screen) and should be on the mailing list instead. Jira
is for when you want to say something more like "I can reproduce this clearly
wrong behavior with these steps A, B, C", "after discussion with others I'd
like to propose feature X" or "I have a solution for Y" However, I just filed
SOLR-13159 which might be related. Can you provide output from
# /admin/collections?action=CLUSTERSTATUS
# The autoscaling.json file from zookeeper
# the output of api/cluster/autoscaling/diagnostics
for comparison?

> Key: SOLR-13142
> URL: https://issues.apache.org/jira/browse/SOLR-13142
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: SolrCloud
> Affects Versions: 7.6
> Reporter: Lyle
> Priority: Major
>
> I have a solr cluster with two nodes, and both of them are alive.
> Solr cluster:
> [http://10.58.91.47:8082/search]
> [http://10.58.91.83:8082/search]
>
> In solr7.5 when create a collection in two nodes cluster with shards=1 and
> replicationFactor=2, each node will have a replica.
> However, in solr7.6, when use same request to create collection, two replicas
> will be put in same solr node.
> example:
> create collection request:
> [http://10.58.91.47:8082/search/admin/collections?action=CREATE&name=NewCollection&numShards=1&replicationFactor=2&collection.configName=conf&shards=shard1&maxShardsPerNode=1]
