Hi Jason, 
I tried to do that. 
JanusGraphManagement janusGraphManagement=janusGraph.openManagement();
janusGraphManagement.set("index.search.index-name", "titan");
janusGraphManagement.commit();


But I got error - 
Caused by: java.lang.IllegalArgumentException: Cannot change offline config option [root.index.index-name] since multiple instances are currently open: [c0a838679548-NOIARAWA3569221, c0a8386711772-NOIARAWA3569221, c0a8386712068-NOIARAWA3569221, c0a8386712596-NOIARAWA3569221]

If I close the graph, then set , I get another error - 
janusGraph.close();
JanusGraphManagement janusGraphManagement=janusGraph.openManagement();
janusGraphManagement.set("index.search.index-name", "titan");
janusGraphManagement.commit();

Caused by: java.lang.IllegalStateException: Environment is closed.

I am not sure how to move ahead. 

Thanks
