Hi Arghya, I'm not sure if you received a reply or not, but here is a Text-based Vertex Adjacency List that I created:
https://github.com/duncanmckie/giraph/blob/release-1.1/giraph-examples/src/main/java/org/apache/giraph/examples/io/formats/TextTextNullTextInputFormat.java This takes a tab-separated, vertex-oriented adjacency list as an input, and (as per your example) does not expect any edge weights. You can easily create your own input format by customising the examples provided, changing the Writable classes and doing any preprocessing as required.

I want a input-format-class where vertex-id, vertex-value and edge-weight everything will be simple text. Eg. I have a simple Graph like following: AAA AAT AAG AAC ACG ACT AAG AGT AGA AAT ATT ACG CGA ACT CTG CTT CTC The first column is the vertex id and the following are the edges (Adjacency list). As you can see edge weight or vertex id can be null also. Is there any predefined input-format in giraph for this? If so what is that? And if not can anybody provide a simple class for that? --> It is not possible to come up with different integer ids for different nodes. Because the vertex id can be even more than 50 characters (It is just a simple excerpt). So I need a very simple text based vertex input format where each line represents a vertex and its outgoing edges (adjacency list). -- Thanks and regards, Arghya Kusum Das (225-270-6163)
