-------------------------------------------------------------------
I have also just encountered this issue on version 5.5.2 when using solrCloud
and a ManagedIndexSchemaFactory. The configset included a schema.xml which was
used to produce a managed-schema file in the config folder on zk, however the
modify to the schema failed as it was still looking for schema.xml.
To workaround the issue I took the managed-schema that was introduced and
placed it in my initial configset, dropped the collection, recreated it, and
tried the update to schema again which worked without issue.

> Issue Type: Bug
> Reporter: Zilo Zongh
> Assignee: Steve Rowe
> Priority: Major
>
> 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
