Hi Jerry

Thanks for helping me out. 

When I manually run 'flush' on the table on the hbase shell, The data persists after system reboot in my local machine. Is there any command to flush the table in gremlin? 

Thanks again

I am not sure what storage model you use for HBase on AWS.

If you are using this: http://docs.aws.amazon.com/emr/latest/ReleaseGuide/emr-hbase-s3.html

There is a section 'Shutting Down and Restoring a Cluster Without Data Loss'.

Basically you want to flush the hbase table before you shut down the cluster.  This is specific to this storage model for HBase on AWS.

I don't see why it happens on your local machine. The above step is not really needed on a local machine.

Try bringing up the 'hbase shell' to see if the data is persisted by running a 'scan' or 'count' on the janusgraph table.  Run a 'flush' on the table.  Then see if it endures a reboot on you local machine.

Thanks.

Yes I am able to run all operations successfully. I tried on on both AWS server and my local machine. AWS server stores hbase data in s3, and I configured the local machine to point to a directory in /home.  
Is there anything I missed to persist data after reboots?

g.V() always returns empty after reboot
