Hi Roman,
Thanks for the quick response. There is no vertex data in this
dataset though, and the vertex IDs posted above would fit in a
Long. Would you advise changing the PageRankComputation
formats, or working on a new input format ?
Thanks,
Kenrick

One of the slightly annoying things in Giraph is that you have
to manually match your input format to your computation. In
your case, PageRankComputation requires LongWritable for
vertex ID and DoubleWritable for vertex Data. You may need
to hack one of the existing formats slightly.
Thanks,
Roma
Hello,
Im trying to get Giraph to read the Twitter dataset as input for the
SimplePageRankComputation program. The dataset format looks like this:
61578010 61147436
61578037 61147436
61578040 61147436
(vertex id's, with pairs representing edges)
When I run the command with
*-vif org.apache.giraph
