Amani  commented on GIRAPH-193:
-------------------------------

Yes, it was 2 mappers. However, I installed zookeeper, and then reinstall 
Giraph again. It works now maximum workers is 3 and more than 500000 a java 
heap exception occurs. 
I have question regarding the graph generated how it looks like? 
Thanks for your input!

> Hi : )
> I'm newbie to Giraph. I installed Giraph by following its ReadMe instructions 
> ( no Zookeeper installation explicitly, is it packed with Giraph?). 
> However, I got problem while running the PageRankBenchmark( -w 2 ), only one 
> worker is running  and the following message shown:
> "failed to report status for 600 seconds. Killing!"
> Hadoop map task list:
> Master_Zookeeper_Only -0 finished 1 0n superstep -1 | complete 100%
> setup: connected to Zookeeper service | complete 0% 
> It has been run on single machine.
> Thanks in advance!
