Michael Della Bitta created SOLR-4409:
-----------------------------------------
Summary: Collection creation should succeed if number of shards ==
number of nodes, regardless of replicationFactor.
Key: SOLR-4409
URL: https://issues.apache.org/jira/browse/SOLR-4409
Project: Solr
Issue Type: Bug
Components: SolrCloud
Affects Versions: 4.1
Environment: 3 node SolrCloud using 4.1 and Tomcat 7, external 3 node
zookeeper, running in AWS.
Reporter: Michael Della Bitta
Priority: Minor
I was expecting that manually calling the Collections API to create a
collection with the replicationFactor set to a value higher than
numShards/number of nodes would create the collection with no replicants and
cap the overall possible number of replicants when the cluster grows larger.
Instead I received this message:
"SEVERE: Cannot create collection $foo. Value of maxShardsPerNode is 1, and the
number of live nodes is 3. This allows a maximum of 3 to be created. Value of
numShards is 3 and value of replicationFactor is 2. This requires 6 shards to
be created (higher than the allowed number)"
Not sure what the thinking behind this is, and maybe I'm just not getting it,
but I would assume collection creation would succeed if the collection is a
valid collection.
