The first one looks like IntNullTextEdgeInputFormat. For the second on= e you can do something similar to =3BAdjacencyListTextVertexInputFormat= =2C except that you don't have edge values.
=0A=
It's not a requirement to have the input split across several files. I= t's desired if you have a big dataset=2C but HDFS should handle that.

Hi all=2C
=0A=
=0A= What are the input formats to use for edge lists and adjacency lists in the= following layout:
=0A=
=0A= For Edge List (undirected):
=0A=
=0A= 1 =3B 3
=0A= 3 =3B 2
=0A= 4 =3B 8
=0A= 5 =3B 3
=0A= . =3B =3B .
=0A= . =3B =3B .
=0A= . =3B =3B .
=0A=
=0A= and for adjacency lists like:
=0A=
=0A= 1 =3B =3B 2
=0A= 2 =3B =3B 3
=0A= 3 =3B =3B 1  =3B 2  =3B 5  =3B
=0A= 4  =3B 8
=0A= 5 =3B =3B 3
=0A= . =3B =3B =3B .
=0A= . =3B =3B =3B .
=0A= . =3B =3B =3B .
=0A=
=0A= and other question=2C is it requirement to have the network divided in seve= ral part files in hdfs?
=0A=
=0A= Thanks very much for your help.
