Zilo Zongh created SOLR-7536:
--------------------------------
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
