Information related to the exception thrown.

Used in: GiraphMasterScenario, GiraphVertexScenario

• required string message = 1

• required string stackTrace = 2

GiraphMasterScenario captures the necessary information to replicate the environment under which user's Master.compute() function was called.

• required string masterClassUnderTest = 1

• required CommonVertexMasterContext commonContext = 2

• optional Exception exception = 3

GiraphVertexScenario captures necessary information to replicate the environment under which user's Computation.compute() function was called on a particular vertex and superstep.

• required GiraphVertexScenario.VertexScenarioClasses vertexScenarioClasses = 1

• required GiraphVertexScenario.VertexContext context = 2

• optional Exception exception = 3

VertexContext encapsulates a particular pair of inputs and outputs of Computation.compute().

Used in: GiraphVertexScenario

• required CommonVertexMasterContext commonContext = 1

• required bytes vertexId = 2

• required bytes vertexValueBefore = 3

• optional bytes vertexValueAfter = 4

• repeated VertexContext.Neighbor neighbor = 5

  TODO: We might have to break neighbor also to neighborsBefore and neighborsAfter.

• repeated bytes inMessage = 6

• repeated VertexContext.OutgoingMessage outMessage = 7

The outgoing neighbors of the current vertex.

Used in: VertexContext

• required bytes neighborId = 1

• optional bytes edgeValue = 2

Messages sent by the current vertex.

Used in: VertexContext

• required bytes destinationId = 1

• required bytes msgData = 2

VertexScenarioClasses contains the names of the user's Computation, Vertex, Vertex ID, Vertex Value, Edge Value, Incoming Message, and Outgoing Message.

Used in: GiraphVertexScenario

• required string classUnderTest = 1

  The class under test. Must implement org.apache.giraph.graph.Computation interface.

• required string vertexIdClass = 2

  The vertex ID class (usually denoted as I). Must implement org.apache.hadoop.io.WritableComparable.

• required string vertexValueClass = 3

  The vertex value class (usually denoted as V). Must implement org.apache.hadoop.io.Writable.

• required string edgeValueClass = 4

  The edge value class (usually denoted as E). Must implement org.apache.hadoop.io.Writable.

• required string incomingMessageClass = 5

  The incoming message class (usually denoted as M1). Must implement org.apache.hadoop.io.Writable.

• required string outgoingMessageClass = 6

  The outgoing message class (usually denoted as M2). Must implement org.apache.hadoop.io.Writable.

Stores a list of messages that are violating an integrity constraint designed by the user.

• required string vertexIdClass = 1

• required string outgoingMessageClass = 2

• required int64 superstepNo = 3

• repeated MessageIntegrityViolation.ExtendedOutgoingMessage message = 4

  Called Extended because in scenario.proto there is another message called OutgoingMessage, which does not have the srcId.

Used in: MessageIntegrityViolation

• required bytes srcId = 1

• required bytes destinationId = 2

• required bytes msgData = 3
