Re: olap connection with spark standalone cluster
This exception is not really related to this thread.
JanusGraph with SparkGraphComputer can only be used with the TinkerPop HadoopGraph. Therefore, the example in the JanusGraph ref docs has a properties file starting with the following lines:
gremlin.graph=org.apache.tinkerpop.gremlin.hadoop.structure.HadoopGraph gremlin.hadoop.graphReader=org.janusgraph.hadoop.formats.cassandra.Cassandra3InputFormatSome of the other JanusGraph storage backends have their own InputFormat.
If you encounter other problems please include the properties file and calling code.
Best wishes, Marc
