Hi guys, i'm testing my Single Node Cluster Giraph installation using PageRankBenchmark example, in the following way:
*$HADOOP_HOME/bin/hadoop jar /usr/local/hadoop/share/hadoop/mapreduce/giraph-examples-1.1.0-for-hadoop-2.4.0-jar-with-dependencies.jar org.apache.giraph.benchmark.PageRankBenchmark -v -V 1000 -e 1 -s 5 -w 1* But after's the mappers complete their job, reducer's don't start. My question is, this is correct? Because i understand that if a mapper get executed, a reducer has to start to take the map's output as an input and finish the work. But i google it, and always PageRankBenchmark (and ShortestPathExample too) ends with Reduce at 0%. Here it's an example : http://stackoverflow.com/questions/25084629/classnotfoundexception-running-giraphrunner-on-a-modified-simpleshortestpathsver So, i don't no if it's ok that in PageRankBenchmark and ShortestPathExample says that Reduce is at 0% I'm using hadoop 2.4, with Phadoop_yarn profile. Hope someone could help me. Bye! Jose
