PageRank on custom input

Hi, 

We want to run a PageRank job (similar to PageRankBenchmark) for custom input graph. Is there an example for this? Giraph's website has a page for this but it is incomplete - http://giraph.apache.org/pagerank.html 

Thanks,

Hi Vikesh, 

You just need to write an input format or use an existing one. You can specify any number and combination of VertexInputFormat and EdgeInputFormat formats as per your needs. 

Please see giraph-core/src/main/java/org/apache/giraph/io/formats for some examples.
