Help needed running Pagerank benchmarks

[Gustavo Enrique Salazar Torres <gs...@ime.usp.br>]

Hi there:

I'm running a little test on a hadoop 2.2.0 installation with Giraph
1.1.0-snapshot.
Here is the command I'm running:

hadoop jar
giraph-examples-1.1.0-SNAPSHOT-for-hadoop-2.2.0-jar-with-dependencies.jar
org.apache.giraph.benchmark.PageRankBenchmark -Dgiraph.zkList=127.0.0.1:2181
-e 3 -s 10 -v -V 1000000 -w 8

This is my mapred-site.xml:

<property>
  <name>mapreduce.framework.name</name>
   <value>yarn</value>
</property>

<property>
<name>mapreduce.jobtracker.address</name>
<value>localhost:54311</value>
</property>

<property>
<name>mapreduce.tasktracker.map.tasks.maximum</name>
<value>10</value>
</property>


<property>
<name>mapreduce.tasktracker.map.tasks.minimum</name>
<value>10</value>
</property>

<property>
<name>mapreduce.job.maps</name>
<value>10</value>
</property>

and I'm getting this at the application log:

org.apache.giraph.master.BspServiceMaster: checkWorkers: Only found 5
responses of 8 needed to start superstep -1.  Reporting every 30000 msecs,
535020 more msecs left before giving up

And finally the job finishes with an error (after a long wait).
Did anybody have this problem?

This doesn't happen if I run the benchmark with 5 workers. I couldn't find
any hint why it works with 5 and not with 6 or more.

Thanks for any help.

Gustavo
