Hi Harsh,

It's currently not possible to combine multiple vertex values, but it = is on our roadmap.
For now, you could try using MapReduce to aggregate those values befor= e you feed them to the Giraph job.

Subject: Regarding multiple values = of a vertex

Hi All,

I am taking input graph in the form of 2 separate files &qu= ot;Edge-List" and "Vertex-List". 
In Vertex-List file, a vertex can have multiple values (val= ue of vertex is of text format) i.e. there can be multiple entries of verte= x-value pair for same vertex.

While taking input of a vertex in Giraph, it checks whether= if vertex is already present in graph, then it replaces the old value with=  new value of vertex. I want to append all the vertex values for the = same vertex (String format). 

I can do it by changing the giraph-core's source code. But,= I am looking for a solution in which while taking input using vertex-input= class, it is possible retrieve old value of that vertex. Is it possible to= do what I am proposing ? Can I retrieve the value of vertex using Vertex Id in vertex-input class ?



Thanks
