Constructor Detail

ZkSolrResourceLoader

public ZkSolrResourceLoader(Path instanceDir,
                            String configSet,
                            ClassLoader parent,
                            ZkController zooKeeperController)

This loader will first attempt to load resources from ZooKeeper, but if not found will delegate to the context classloader when possible, otherwise it will attempt to resolve resources using any jar files found in the "lib/" directory in the specified instance directory.

Method Detail

openResource

public InputStream openResource(String resource)
                         throws IOException

Opens any resource by its name. By default, this will look in multiple locations to load the resource: $configDir/$resource from ZooKeeper. It will look for it in any jar accessible through the class loader if it cannot be found in ZooKeeper. Override this method to customize loading resources.

Specified by:

openResource in interface org.apache.lucene.util.ResourceLoader

Overrides:

openResource in class SolrResourceLoader

Returns:

the stream for the named resource

Throws:

IOException
