Morphiastic - is it worth trying it

Hi,
I am trying to use Morphiastic ElasticStore class together with the elasticsearch library, with no success so far. Has anybody tried this? I am consistently getting an error:
INFO: LoggerImplFactory set to com.google.code.morphia.logging.jdk.JDKLoggerFactory
log4j:WARN No appenders could be found for logger (org.elasticsearch.node).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
