> Allow default GraphComputer configuration
> -----------------------------------------
>
> Key: TINKERPOP-1222
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1222
> Project: TinkerPop
> Issue Type: Bug
> Affects Versions: 3.2.0-incubating
> Reporter: Matthias Broecheler
> Fix For: 3.2.0-incubating
>
>
> so that the user can simply do {{graph.compute()...}} without having to
> specify the graph computer.
> As of 3.0, we HadoopGraph does NOT have a default graph computer. This was
> done to not favor one technology over the other. We could allow the
> configuration to have a
> gremlin.hadoop.defaultGraphComputer=org.tinkerpop.SparkGRaphcomputer
> That configuration would be carried through the various result sets so that
> the user would only have to choose the graph computer initially (or it is
> pre-selected by the graph implementation) and from that point on would be
> defaulted.
