Hi Jason,

Thank You..I have changed the values as you said..still getting same exception..

cassandra keyspace:

CREATE KEYSPACE keyspaceName WITH replication = {'class': 'NetworkTopologyStrategy', 'dc1': '2', 'dc2': '1', 'dc3': '1'}  AND durable_writes = true;

also checked that cassandra nodes are sync and running properly..

Tried to create a new label with new cassandra keyspace(empty keyspace)..but getting below exception:

graph = JanusGraphFactory.open('janus.properties')

mgmt= graph.openManagement()

labelName = mgmt.makeVertexLabel('labelName').make()

mgmt.commit()

Could not commit transaction due to exception during persistence

Type ':help' or ':h' for help.

Display stack trace? [yN]y
