Subject Re: Using the RandomEdge ... & RandomVertex InputFormat
Date Tue, 05 Nov 2013 12:05:04 GMT
Hi,

after I changed the code of the PseudoRandomVertex.... and
PseudoRandomEdgeInputFormat I can compile and run the job but it will stop
after the 10 minute timeout.

I think there is still some parameter missing or defined wrong.

Claudio wrote, one has to set the number of vertexes, but how?

This my call:

hadoop jar giraph-ex.jar org.apache.giraph.GiraphRunner -Dgiraph.zkList=
127.0.0.1:2181 -libjars giraph-core.jar org.apache.giraph.examples.SSPV2
-vif org.apache.giraph.io.formats.PseudoRandomVertexInputFormat2
-eif org.apache.giraph.io.formats.PseudoRandomEdgeInputFormat2
-of org.apache.giraph.io.formats.IdWithValueTextOutputFormat
-op /user/cloudera/goutput/shortestpaths_rand_$NOW
-w 1
-ca giraph.pseudoRandomInputFormat.edgesPerVertex=100
-ca giraph.pseudoRandomInputFormat.aggregateVertices=2
-ca giraph.pseudoRandomInputFormat.localEdgesMinRatio=200

What parameter defines the number of vertexes, I want to create?
My test graph should have 1000 nodes.

There are no exceptions, but also no vertexes are created.

The code runs and gives the following log:
