Hi there,
I have come accross a problem that when using managed schema in SolrCloud,
adding fields into schema would SOMETIMES end up prompting "Can't find
resource 'schema.xml' in classpath or '/configs/collectionName',
cwd=/export/solr/solr-5.1.0/server", there is of course no schema.xml in
configs, but 'schema.xml.bak' and 'managed-schema'
i use solrj to create a collection:
Path tempPath = getConfigPath();
client.uploadConfig(tempPath, name); //customized configs with
solrconfig.xml using ManagedIndexSchemaFactory
if(numShards==0){
numShards = getNumNodes(client);
}
Create request = new CollectionAdminRequest.Create();
request.setCollectionName(name);
request.setNumShards(numShards);
replicationFactor =
(replicationFactor==0?DEFAULT_REPLICA_FACTOR:replicationFactor);
request.setReplicationFactor(replicationFactor);
request.setMaxShardsPerNode(maxShardsPerNode==0?replicationFactor:maxShardsPerNode);
CollectionAdminResponse response = request.process(client);
and adding fields to schema, either by curl or by httpclient, would
sometimes yield the following error, but the error can be fixed by
RELOADING the newly created collection once or several times:
INFO - [{ "responseHeader":{ "status":500, "QTime":5},
"errors":["Error reading input String Can't find resource 'schema.xml' in
classpath or '/configs/collectionName',
cwd=/export/solr/solr-5.1.0/server"], "error":{ "msg":"Can't find
resource 'schema.xml' in classpath or '/configs/collectionName',
cwd=/export/solr/solr-5.1.0/server", "trace":"java.io.IOException: Can't
find resource 'schema.xml' in classpath or '/configs/collectionName',
cwd=/export/solr/solr-5.1.0/server
