Re: A simple use case: shortest paths on a FOAF (i.e. Friend of a Friend) graph

Hi Avery, nope, no luck. I have changed all my log.debug(...) into log.info(...). Same behavior. I have a log4j.properties [1] file in my classpath and it has: log4j.logger.org.apache.jena.grande=DEBUG log4j.logger.org.apache.jena.grande.giraph=DEBUG I also tried to change that to:

Does Giraph support labeled graphs?

2012-04-11 Thread Paolo Castagna
Hi, I am not sure what's the best way to represent labeled graphs in Giraph. Here is my graph (i.e. vertex_id --edge_label_id-- vertex_id ): 32 --62-- 115 32 --153-- 189 32 --200-- 236 32 --266-- 303 32 --266-- 331 32 --266-- 363 303 --153-- 407 303 --266-- 331 331 --153-- 394 331 --266-- 32 ...

It shouldn't be, your code looks very similar to the unittests (i.e. TestManualCheckpoint.java). So, you're trying to run your test with the local hadoop (similar to the unittests)? Or are you using an actual hadoop setup? Avery On 4/10/12 11:41 PM, Paolo Castagna wrote: I am using

There is no preferred way to represent labeled graphs. A close example to your adjacency list idea is LongDoubleDoubleAdjacencyListVertexInputFormat. Hope that helps, Avery On 4/11/12 10:00 AM, Paolo Castagna wrote: Hi, I am not sure what's the best way to represent labeled graphs in
