Thanks for the info. It seems I'm unable to run
...examples.SimpleShortestPathsVertex with these input formats, is there a
converter available to convert from these formats to VertexInputFormat.
I mean I tried with the converted undirected edge list to the [3,0,[[843,0]]]
format but I'm getting the following error:
"Exception in thread "main" java.lang.NullPointerException"
Thanks in advance for your advise.

The first one looks like IntNullTextEdgeInputFormat. For the second one you can
do something similar to AdjacencyListTextVertexInputFormat, except that you
don't have edge values.
It's not a requirement to have the input split across several files. It's
desired if you have a big dataset, but HDFS should handle that.

Hi all,
What are the input formats to use for edge lists and adjacency lists in the
following layout:
For Edge List (undirected):
1 3
3 2
4 8
5 3
. .
. .
. .
and for adjacency lists like:
1 2
2 3
3 1 2 5
4 8
5 3
. .
. .
. .
and other question, is it requirement to have the network divided in several
part files in hdfs?
Thanks very much for your help.
Regards
