java - Java 経由で Lucene を使用するための JanusGraph の構成

Question

次のコードを使用して JanusGraph に接続しようとしています。

Graph graph = GraphFactory.open(new PropertiesConfiguration("janusgraph.propertes");

私のjanusgraph.propertiesファイルは次のとおりです。

gremlin.graph=org.janusgraph.core.JanusGraphFactory
storage.backend=hbase
storage.hostname=127.0.0.1

cache.db-cache = true
cache.db-cache-clean-wait = 20
cache.db-cache-time = 180000
cache.db-cache-size = 0.5

index.janusgraph-index.backend=lucene

ただし、接続しようとすると、次のエラーが表示されます。

これは、Lucene ではなく Elasticsearch を使用しようとしているようです。Lucene を使用するように正しく構成するにはどうすればよいですか?
