Subject Problem with giraph deployment on the cluster
Date Wed, 05 Feb 2014 13:49:38 GMT

I have deployed Giraph on the 8-node cluster (Giraph:
release-1.0.0-RC2-152-g585511f, Hadoop: As I do not have
Internet on the cluster I have copied Giraph from my local computer where
it worked well.

Now I am trying to test it on the cluster and have following issues:

1) When I running Giraph (with -h, just to test) it starts very slowly
comparing to my local machine.
2) When I running a simple test it hangs like this:

frolo@A11:~> $HADOOP_HOME/bin/hadoop jar
org.apache.giraph.examples.SimpleShortestPathsComputation -vif
-vip /user/frolo/input/tiny_graph.txt -vof -op
/user/frolo/output/shortestpaths -w 1

(default), do not allow any task retries (setting =

and nothing happens.

I would appreciate any help in tracking down this issue. Thank you.
