Difference in Input format and Vertex type

Hi, Using giraph, I am taking input in the format TextDoubleDoubleAdjacencyListVertexInputFormat and I want my Vertex to be of type VertexText,Text,DoubleWritable,Text i.e vertex value in input is in DoubleWritable and in program it is of type Text. Can this be done in giraph i.e will giraph type

how to change graph

Hi, I wanted to do some computation on graph and delete some edges between supersteps. Can this be done using giraph?? I have heard of MutableVertex class but I dont know whether it can be used to delete edges. Also is MutableVertex abstract class and has to be implemented?? Regards, Akshay

Can a vertex belong to more than one partition

In order to custom partition the graph, WorkerGraphPartitioner has to be implemented. It has a method getPartitionOwner(I vertexId) which returns PartitionOwner of the vertex. I want that some vertices belong to all paritions i.e all PartitionOwners. Can anyone help me with it?

Custom partitioning among workers

Hi all, I need help on partitioning graph. I input the graph and label it. Now I want that all vertices with same label are assigned to a worker and no other vertices with different labels are assigned to the same worker. In this way each group of vertices having same label are assigned to an

how to input two graphs using giraph

Hi, I want to solve sub-graph isomorphism through giraph so I need to input two graphs-Data Graph(having million of nodes) and Query Graph(having few nodes). Can anyone help me on how to take the data graph and query graph as input(Both are saved two different files in JsonLongDoubleFloatDouble
