Bernd Fehling commented on SOLR-10733:
--------------------------------------
OK, two versions for testing the result of the rules, which one do you
accept/prefer?
version1)
{code}
int shard1_replica_count = 0;
for (Position key : mapping.keySet()) {
if(key.toString().contains("shard1")) {
if(mapping.get(key).contains("49961")) {
shard1_replica_count += key.index;
}
assertTrue(mapping.get(key).contains("49961"));
}
}
assertTrue(shard1_replica_count < 2);
int shard3_replica_count = 0;
for (Position key : mapping.keySet()) {
if(key.toString().contains("shard3")) {
if(mapping.get(key).contains("49955")) {
shard3_replica_count += key.index;
}
assertTrue(mapping.get(key).contains("49955"));
}
}
assertTrue(shard3_replica_count < 2);
{code}
version 2)
{code}
int shard1_replica_count = 0;
for (Position key : mapping.keySet()) {
if(key.toString().contains("shard1")) {
shard1_replica_count += key.index;
assertTrue(mapping.get(key).contains("49961"));
}
}
assertTrue(shard1_replica_count < 2);
int shard3_replica_count = 0;
for (Position key : mapping.keySet()) {
if(key.toString().contains("shard3")) {
shard3_replica_count += key.index;
assertTrue(mapping.get(key).contains("49955"));
}
}
assertTrue(shard3_replica_count < 2);
{code}
> Rule-based Replica Placement not working correct

> Key: SOLR-10733
> URL: https://issues.apache.org/jira/browse/SOLR-10733
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: Rules, SolrCloud
> Affects Versions: 6.5.1
> Reporter: Bernd Fehling
> Assignee: Noble Paul
> Attachments: SOLR-10733.patch, SOLR-10733.patch

> A setup of a SolrCloud with 6 nodes on 3 server e.g.:
> {code}
> server1:8983 , server1:7574
> server2:8983 , server2:7574
> server3:8983 , server3:7574
> {code}
> and a command for creating a new collection with rule:
> {code}
> http://localhost:8983/solr/admin/collections?action=CREATE&name=boss&;
> collection.configName=boss_configs&numShards=3&replicationFactor=2&
> maxShardsPerNode=1&rule=shard:shard1,replica:<2,port:8983
> {code}
> should create a collection with 3 shards and least a shard1 with two
> different nodes running on port 8983.
> {code}
> shard1 --> server_x:8983 , server_y:8983
> {code}
> A even more restrictive rule like
> {code}
> rule=shard:shard1,replica:<2,port:8983&rule=shard:shard3,replica:<2,port:7574
> {code}
> should also resolve to a solution because if it really checks all
> permutations accross shards/replicas/ports and available nodes it should be
> able to solve this.
