Method Detail

openResource

public InputStream openResource(String resource)

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 ResourceLoader

Returns:

the stream for the named resource

Throws:

IOException
