--------------------------------

             Summary:  adding fields to newly created managed-schema could sometimes cause error
                 Key: SOLR-7536
                 URL: https://issues.apache.org/jira/browse/SOLR-7536
             Project: Solr
          Issue Type: Bug
            Reporter: Zilo Zongh


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'

Code to upload configs and create 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);

 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
