A slight correction and clarification of my previous post - the total number of partitions/splits is exactly equal to total_number_of_tokens + 1. In a 3-node cassandra cluster where each node has 256

Hello, I am trying to run SparkGraphComputer on a JanusGraph backed by Cassandra and ElasticSearch. I have previously verified that I am able to run SparkGraphComputer on a local Spark standalone

Hello Boxuan, I need to support reindexing very large graphs. To my knowledge, the only feasible way that's supported is via the `MapReduceIndexManagement` class. This is not ideal for me as I'd like

Hi Roy, As I mentioned, I did not keep up with possibly new janusgraph-hbase features. From the HBase source, I see that HBase now has a "hbase.mapreduce.tableinput.mappers.per.region" config
