Subject Suggest Vertex input format for TriangleClosingComputataion. Getting " java.lang.IllegalStateException: checkClassTypes: vertex index types not assignable"
Date Thu, 28 Jul 2016 17:32:38 GMT
Hi Team,
I am new to giraph and I am trying to run non-neighbor base algorithm
(SimpleTriangleClosingComputation & ConnectedComponentsComputation) on
giraph(1.2.0) using below command

"/$HADOOP_HOME/bin/hadoop jar
$GIRAPH_HOME/giraph-examples/target/giraph-examples-1.2.0-SNAPSHOT-for-hadoop-2.7.0-jar-with-dependencies.jar
org.apache.giraph.GiraphRunner
org.apache.giraph.examples.SimpleTriangleClosingComputation -vif
org.apache.giraph.io.formats.JsonLongDoubleFloatDoubleVertexInputFormat
-vip /user/hdfs/GraphData/tiny_graph.txt -vof
org.apache.giraph.io.formats.IdWithValueTextOutputFormat -op
/user/hdfs/GraphData/output/ -w 1 -ca giraph.SplitMasterWorker=false"

but i am getting below exception

Logs:
Exception in thread "main" java.lang.IllegalStateException:

I want to know the is vertex format is different for TriangleClosing algo
or graph with some particular property(directed or undirected) is accepted.
Please explain the logs as well.

While i am able to run SSSP and PageRank example successfully. Command I am
using for PageRank is :
"/$HADOOP_HOME/bin/hadoop jar
$GIRAPH_HOME/giraph-examples/target/giraph-examples-1.2.0-SNAPSHOT-for-hadoop-2.7.0-jar-with-dependencies.jar
org.apache.giraph.GiraphRunner
org.apache.giraph.examples.SimplePageRankComputation -vif
org.apache.giraph.io.formats.JsonLongDoubleFloatDoubleVertexInputFormat
-vip /user/hdfs/GraphData/tiny_graph.txt -vof
org.apache.giraph.io.formats.IdWithValueTextOutputFormat -op
/user/hdfs/GraphData/output/ -w 1 -ca giraph.SplitMasterWorker=false -mc
org.apache.giraph.examples.SimplePageRankComputation\$SimplePageRankMasterCompute"

Thanks,
Akash
