Hi, 

I am running the PageRank benchmark under giraph-examples from giraph-1.0.0 
release. I am using the following command to run the job (as mentioned here ) 



vikesh@madmax 
/lfs/madmax/0/vikesh/usr/local/giraph/giraph-examples/src/main/java/org/apache/giraph/examples
 $ $HADOOP_HOME/bin/hadoop jar 
$GIRAPH_HOME/giraph-core/target/giraph-1.0.0-for-hadoop-0.20.203.0-jar-with-dependencies.jar
 org.apache.giraph.benchmark.PageRankBenchmark -e 1 -s 3 -v -V 50000000 -w 30 




However, the job gets stuck at map 9% and is eventually killed by the 
JobTracker on reaching the mapred.task.timeout (default 10 minutes). I tried 
increasing the timeout to a very large value, and the job went on for over 8 
hours without completion. I also tried the ShortestPathsBenchmark, which also 
fails the same way. 




Any help is appreciated.
