Daniel Kuppitz commented on TINKERPOP-1134:
-------------------------------------------
^^ Bad solution, as it doesn't take multiple edges between 2 vertices into
account.
> Edge IDs in HadoopGraph
> -----------------------
>
> Key: TINKERPOP-1134
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1134
> Project: TinkerPop
> Issue Type: Improvement
> Components: hadoop, process
> Affects Versions: 3.0.0-incubating
> Reporter: Daniel Kuppitz
>
> Edge IDs in Hadoop graph have to be consistent. If an out-edge's id differs
> from its respective in-edge id, some traversals will fail. This is especially
> a problem in user generated input files.
> I know how to improve that for {{ScriptInputFormat}}, but what if a user
> generates a custom GraphSON file? Do we want him to take care of the edge ids
> or can we ignore edge ids in HadoopGraph?
