TINKERPOP-1862 Fix Messenger implementations for Spark/Giraph handling BOTH
These now behave like TinkerMessenger and in the case of BOTH pass the message to the opposite vertex in the StarGraph Project: http://git-wip-us.apache.org/repos/asf/tinkerpop/repo Commit: http://git-wip-us.apache.org/repos/asf/tinkerpop/commit/26a5770e Tree: http://git-wip-us.apache.org/repos/asf/tinkerpop/tree/26a5770e Diff: http://git-wip-us.apache.org/repos/asf/tinkerpop/diff/26a5770e Branch: refs/heads/TINKERPOP-1522 Commit: 26a5770efb288d60150cf9db60a5dd67568179f2 Parents: 027ae27 Author: Stephen Mallette <sp...@genoprime.com> Authored: Fri Mar 2 11:29:57 2018 -0500 Committer: Stephen Mallette <sp...@genoprime.com> Committed: Fri Mar 2 11:29:57 2018 -0500 ---------------------------------------------------------------------- .../process/computer/GiraphMessenger.java | 14 +- .../gremlin/process/ProcessComputerSuite.java | 168 +++++++++---------- .../process/computer/GraphComputerTest.java | 41 +++-- .../computer/util/ComputerSubmissionHelper.java | 2 +- .../spark/process/computer/SparkMessenger.java | 12 +- .../spark/structure/io/ToyGraphInputRDD.java | 2 + 6 files changed, 136 insertions(+), 103 deletions(-) ---------------------------------------------------------------------- http://git-wip-us.apache.org/repos/asf/tinkerpop/blob/26a5770e/giraph-gremlin/src/main/java/org/apache/tinkerpop/gremlin/giraph/process/computer/GiraphMessenger.java ---------------------------------------------------------------------- diff --git a/giraph-gremlin/src/main/java/org/apache/tinkerpop/gremlin/giraph/process/computer/GiraphMessenger.java b/giraph-gremlin/src/main/java/org/apache/tinkerpop/gremlin/giraph/process/computer/GiraphMessenger.java index 03818b2..36e641e 100644 --- a/giraph-gremlin/src/main/java/org/apache/tinkerpop/gremlin/giraph/process/computer/GiraphMessenger.java +++ b/giraph-gremlin/src/main/java/org/apache/tinkerpop/gremlin/giraph/process/computer/GiraphMessenger.java @@ -27,6 +27,7 @@ import org.apache.tinkerpop.gremlin.process.traversal.util.TraversalHelper; import org.apache.tinkerpop.gremlin.structure.Direction; import org.apache.tinkerpop.gremlin.structure.Edge; import org.apache.tinkerpop.gremlin.structure.Vertex; +import org.apache.tinkerpop.gremlin.structure.util.star.StarGraph; import org.apache.tinkerpop.gremlin.util.iterator.IteratorUtils; import java.util.Iterator; @@ -57,10 +58,19 @@ public final class GiraphMessenger<M> implements Messenger<M> { final MessageScope.Local<M> localMessageScope = (MessageScope.Local) messageScope; final Traversal.Admin<Vertex, Edge> incidentTraversal = GiraphMessenger.setVertexStart(localMessageScope.getIncidentTraversal().get().asAdmin(), this.giraphVertex.getValue().get()); final Direction direction = GiraphMessenger.getOppositeDirection(incidentTraversal); -
