Using janusgraph-0.1.0-hadoop2 with backend cassandra-3.0.14:

This is the configuration file:

storage.backend=cassandrathrift

storage.hostname=hostName1

storage.cassandra.keyspace=keyspaceName

storage.batch-loading=false

cache.db-cache=true

cache.db-cache-time = 180000

cache.db-cache-size = 0.25

storage.lock.wait-time=300000

storage.lock.retries=10

storage.lock.clean-expired=true

storage.buffer-size=512

ids.block-size=300000

storage.cassandra.compression=false

storage.lock.expiry-time=100

index.search.backend=elasticsearch

index.search.hostname=es-hostName

index.search.elasticsearch.client-only=true

storage.connection-timeout=300000

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
