New APIs will be good. The source code or code snippet on the page is different from the Compute method implemented in the java file: https://github.com/apache/giraph/blob/trunk/giraph-examples/src/main/java/org/apache/giraph/examples/SimpleShortestPathsComputation.java The link you provided is from the trunk and the latest release, I believe. I looked into the release-1.0 of giraph and found this link with the same source or code snippet on the current introductory page: https://github.com/apache/giraph/blob/release-1.0/giraph-examples/src/main/java/org/apache/giraph/examples/SimpleShortestPathsVertex.java Which of the java files provided through the links above should I use and link to on the intro.html? The source or code snippet will need to be modified or not modified depending on the java file. > Broken Link on Introduction Page for User Docs > -- > > Key: GIRAPH-1126 > URL: https://issues.apache.org/jira/browse/GIRAPH-1126 > Project: Giraph > Issue Type: Task > Components: site > Environment: Chrome Browser v54.0.2840.98 on macOS Sierra v10.12.1 >Reporter: Michael Aro >Assignee: Michael Aro >Priority: Trivial > Labels: documentation > > On the Introduction page of the User Docs is a broken link.

[jira] [Commented] (GIRAPH-1126) Broken Link on Introduction Page for User Docs

Simply because Vertex class doesn't have compute() function anymore. So, we should either take this link: https://github.com/apache/giraph/blob/trunk/giraph-examples/src/main/java/org/apache/giraph/examples/SimpleShortestPathsComputation.java and update intro accordingly. Or, much better, rewrite the whole thing using the new API and update intro as well. > Broken Link on Introduction Page for User Docs > -- > > Key: GIRAPH-1126 > URL: https://issues.apache.org/jira/browse/GIRAPH-1126 > Project: Giraph > Issue Type: Task > Components: site > Environment: Chrome Browser v54.0.2840.98 on macOS Sierra v10.12.1 >Reporter: Michael Aro >Assignee: Michael Aro >Priority: Trivial > Labels: documentation > > On the Introduction page of the User Docs is a broken link.
