Hi Marc, The 2.0.alpha release has a dependency on HBase. The macro LOAD_TITAN in Pig can read only from HBase, but it can write to a Titan+Cassandra graph. One way of doing it is to create a new configuration file similar to examples/hbase-titan-conf.xml file provided in the release. Use "cassandra" as the storage backend and the appropriate hostnames and the Pig macro LOAD_TITAN will load it to Titan+Cassandra. Thanks, -Kushal.

I'm using Titan as our graph DB with Cassandra as the Titan backend storage. I noticed that GraphBuilder seems to have some dependency on input data with HBase. Can I use the Titan+Cassandra combination with bulk TITAN_LOAD to input my graphs without needing HBase? Regards, Marc -- J.
