[hibernate-issues] [Hibernate-JIRA] Commented: (HSEARCH-238) DirectoryProviderFactory configuration problem

DirectoryProviderFactory configuration problem ---------------------------------------------- Key: HSEARCH-238 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-238 Project: Hibernate Search Issue Type: Bug Reporter: Rafal Glowacz Assignee: Sanne Grinovero Original Estimate: 1 day Remaining Estimate: 1 day Because IdHashShardingStrategy fails after 1.7m ID is reached I decided to use my own version of strategy. I set up property common.hibernate.search.blogentry.sharding_strategy = com. ... .IdShardingStrategy and didn't work for me. As I checked problem exist in DirectoryProviderFactory and the way how properties are created ( new Properties( defaultProperties ) ). This constructor and the way how default properties are stored in this Object this both together doesn't work well. Problem exist: //define sharding strategy IndexShardingStrategy shardingStrategy; Properties shardingProperties = new Properties(); for (Map.Entry entry : indexProps[0].entrySet()) { if ( ( (String) entry.getKey() ).startsWith( SHARDING_STRATEGY ) ) { shardingProperties.put( entry.getKey(), entry.getValue() ); } } String shardingStrategyName = shardingProperties.getProperty( SHARDING_STRATEGY ); if ( shardingStrategyName == null) { if ( indexProps.length == 1 ) { shardingStrategy = new NotShardedStrategy(); } else { shardingStrategy = new IdHashShardingStrategy(); } } else { in this loop "for (Map.Entry entry : indexProps[0].entrySet()) {" this set is just empty so custom properties for sharding have been ignored. Workaround: Instead using new Properties(defaultProps) I'm using method: private static Properties createProperties(Properties indexSpecificDefaultProps) { Properties properties = new Properties(); properties.putAll(indexSpecificDefaultProps); return properties; }
