Hi community,
I have solr 7.6 running on three nodes with about 400 collections with one
shard and 3 replicas per collection. I want replicas to be spread between
all 3 nodes so that for every collection I have one replica per collection
on each node.
I create collections via the SolrJ code.
for (String collectionName:<list of collection
Names>){
create =
CollectionAdminRequest.createCollection(collectionName, source,
1, 3);
result = solrClient.request(create);
}
In solr 7.4 it worked fine, but in solr 7.6 created replicas are not spread
equally between nodes. In some collections all 3 replicas are created just
on one node, in some 2 replicas are created in one node and 1 in another
and some collections are created correctly: I replica per node.
Could anyone give me advice on why it happened and how to fix it?
Thank you.
Lev Tannen
