Graph does not support the provided graph computer: SparkGraphComputer
Hi, I'm trying to instantiate a janusgraph server that correctly exports a graph.traversal().withComputer(SparkGraphComputer)
As I was unable to find specific documentation on this, I have tried following this:
https://stackoverflow.com/questions/45323666/unable-to-use-sparkgraphcomputer-with-tinkerpop-3-2-3-and-janusgraph-0-1-1-in-re
However, I'm unable to instantiate a graph of this type:

Does anyone have any suggestions on how to properly setup a janusgraph server so that queries are executed using SparkGraphComputer?
BTW: I'm able to correctly run queries from the gremlin console, by following the example in the official janusgraph documentation:
https://docs.janusgraph.org/advanced-topics/hadoop/
But what I'm interested in is instantiating a janusgraph server that by defualt runs all queries on a given traveral source using SparkGraphComputer.

Solution
OK, finally I was able to figure out the issue on my own. To make things work, since JanusGraphFactory fails to create a graph, I replaced
