Hi all

I am new to Janusgraph/ Titan, 

I installed janusgraph 0.1.0 in aws EMR, using db backend hbase and index backend solr. 

Everything works, But when I reboot the system, All the graph data is lost , g.V() returns empty array.

Hbase is configured to use S3, and I configured solr based on this link https://blog.codecentric.de/en/2016/02/getting-started-titan-using-cassandra-solr/

My gremlin-server conf is:

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.search.backend=solr

index.search.solr.mode=http

index.search.solr.http-urls=http://localhost:8983/solr

How can I persist data between system restarts?
