Hello all, in Solr Cloud mode I always get an additional data-directory named *_shard1_replica_n1 for every core which is then used as data-directory. In Standalone mode everything is working fine.
- Standalone bin/solr start -force curl http://localhost:8983/solr/admin/cores curl http://localhost:8983/solr/testcore/update?commit=true --data-binary '[ { "id": "1", "text": "example" } ]' -H 'Content-type:application/json' curl http://localhost:8983/solr/testcore/select?q=* - Cloud mode With an empty core.properties I get 1. No coreNodeName for CoreDescriptor[name=testcore;instanceDir=/var/solr/data/testcore] 2. No shard id for CoreDescriptor[name=testcore;instanceDir=/var/solr/data/testcore] So core.properties needs to be populated: cat <<EOF > /var/solr/data/testcore/core.properties coreNodeName=core_node1 collection.configName=testcore name=testcore numShards=1 shard=shard1 collection=testcore replicaType=NRT EOF Start in cloud mode: bin/solr start -c -force An error is occurs, because I think the collection needs to be created: > coreNodeName core_node1 does not exist in shard shard1, ignore the exception > if the replica was deleted So creating the collection: bin/solr create -c testcore -d /var/solr/data/testcore -force > Created collection 'testcore' with 1 shard(s), 1 replica(s) with config-set > 'testcore' After that there is an additional data-directory named *_shard1_replica_n1: ls /var/solr/data/ > testcore testcore_shard1_replica_n1 zoo_data The original directory "testcore" is never used again and can even be deleted. Does anyone has an idea how Solr in cloud mode can be configured to use the original directory without creating a new one? Thanks, Alex My test-environment for Solr with Docker: docker run --rm -it --user root solr:latest /bin/bash mkdir -p /var/solr/data/testcore/conf touch /var/solr/data/testcore/core.properties cat <<EOF > /var/solr/data/testcore/conf/solrconfig.xml <?xml version="1.0" encoding="UTF-8"?> <config> <luceneMatchVersion>9.8</luceneMatchVersion> <schemaFactory class="ClassicIndexSchemaFactory"/> <updateHandler class="solr.DirectUpdateHandler2"> <updateLog> <str name="dir">\${solr.ulog.dir:}</str> </updateLog> </updateHandler> <requestHandler name="/select" class="solr.SearchHandler" default="true"> <lst name="defaults"> <str name="defType">edismax</str> <str name="df">text</str> <str name="q.op">AND</str> </lst> </requestHandler> </config> EOF cat <<EOF > /var/solr/data/testcore/conf/schema.xml <?xml version="1.0" encoding="UTF-8"?> <schema name="testcore" version="1.2"> <uniqueKey>id</uniqueKey> <field name="id" type="string" indexed="true" required="true" stored="true"/> <field name="_version_" type="long" indexed="true" stored="true" multiValued="false"/> <fieldType name="int" class="solr.IntPointField" docValues="true"/> <fieldType name="long" class="solr.LongPointField" docValues="true"/> <fieldType name="string" class="solr.StrField" omitNorms="true"/> <fieldType name="text" class="solr.TextField" positionIncrementGap="100"/> <field name="text" type="text" multiValued="true" indexed="true" stored="true"/> </schema> EOF
