GraphBuilder output -> GraphLab input
by Rebecca Dengate
Hi there,
I am looking at using GraphBuilder and GraphLab2 for distributed
computer vision at NICTA. I have been trying to get a simple example to
work in order to understand how the pipeline works. I generate a graph
using:
"hadoop jar graphbuilder-0.0.1-SNAPSHOT-hadoop-job.jar
com.intel.hadoop.graphbuilder.demoapps.wikipedia.linkgraph.LinkGraphEnd2End
4 /user/hduser/wiki-input /user/hduser/wiki-output"
where wiki-input contains
enwiki-latest-pages-articles1.xml-p000000010p000010000 downloaded from
wikipedia.
I'm then trying to load the graph from wiki-output in GraphLab2 (to,
say, run pagerank). I am using load_json for this, but it expects a
structure that looks like:
graph/graph[processID]-r-0000x[optional .gz]
graph/vid2lvid[processID]-r-0000x[optional .gz]
graph/edata[processID]-r-0000x[optional .gz]
graph/vdata[processID]-r-0000x[optional .gz]
where x is (I think) the partition number.
This doesn't at all match what is output by GraphBuilder, which is (for
graph_partitioned):
edges -> partition0 -> subpart0-x
edges -> vrecord -> part-00000
vrecords -> partition0-x -> vrecord
vrecords -> partition0-x -> meta
The edges -> vrecord -> part-00000 seems to match what's expected for
graph/vdata[processID]-r-0000x[optional .gz] (except for keyword vdata
rather than VertexData) but the rest do not seem to correspond to what
GraphLab expects.
According to docs for GraphBuilder, the graph formats are both GraphLab2
based (GLGraph says it's a GraphLab2 distributed graph, and SimpleGraph
says it's a pre-finalized, post-partitioned GraphLab2 graph). I've tried
changing SimpleGraph to GLGraph in EdgeIngressReducer.java and
EdgeIngressMR.java, but this doesn't change the structure of the files
output by GraphBuilder.
I'm sure I'm doing something wrong here, but I can't see what it is (I'm
fairly new to graph processing). Any help appreciated in getting
GraphBuilder output to work as GraphLab2 input!
Thanks,
Rebecca
