titan with es and cassandra - java.lang.IllegalArgumentException: Index is unknown or not configured: search - titan

Question

I am using es-cassandra. I am trying to load the default graph but I get the below error. How do I fix? I am assming I have to create a ES index? if so then what index?
curl -XPUT 'http://localhost:9200/WHAT_INDEX???/'
gremlin> g = GraphOfTheGodsFactory.create('/tmp/titan')
==>titangraph[local:/tmp/titan]
gremlin> g = TitanFactory.open('conf/titan-cassandra-es.properties')
==>titangraph[local:/home/ubuntu/conf/titan-cassandra-es.properties]
gremlin> GraphOfTheGodsFactory.load(g)
Index is unknown or not configured: search

Not sure I'm following what you're trying to do. You've already initialized g with
g = GraphOfTheGodsFactory.create('/tmp/titan')
With that you've create Graph of the Gods with BerkeleyDB. Why are you then re-initializing it with cassandra?
If I first start an instance of cassandra, then execute:
gremlin> g = TitanFactory.open('conf/titan-cassandra-es.properties')
==>titangraph[cassandrathrift:127.0.0.1]
gremlin> GraphOfTheGodsFactory.load(g)
==>null
Note the difference as compared to your gremlin session:
gremlin> g = TitanFactory.open('conf/titan-cassandra-es.properties')
==>titangraph[local:/home/ubuntu/conf/titan-cassandra-es.properties]
It actually looks like it's not finding the configuration file at conf/titan-cassandra-es.properties and is then creating a BerkeleyDB instance. You will likely find a directory at: /home/ubuntu/conf/titan-cassandra-es.properties with berkeleydb data files in it. Check the location of the actual conf/titan-cassandra-es.properties and make sure it is there.
