Hi John,
yes i've gotten the examples but the job failed this was my command:
bin/hadoop jar
/usr/local/giraph/giraph-core/target/giraph-1.1.0-SNAPSHOT-for-hadoop-1.2.1-jar-with-dependencies.jar
org.apache.giraph.GiraphRunner
org.apache.giraph.benchmark.ShortestPathsComputation -vif
ok john the problem for the example of ShortestPathsComputation was
mapred.map.max.attempts property...now it runs well

Hi Carmen,
I think the ChildError is being thrown by Hadoop but the root cause is this
NPE within the BspServiceMaster. Unfortunately, I have not seen this
exception situation and am not sure why you are getting the NPE. It may be
a data issue. Quick question--have you gotten the examples
Hi Carmen,
Glad that one problem is fixed, and I can take a look at this one as well.

ava.lang.Throwable: Child
Hi Carmen,
Please post more of the exception stack trace, not enough here for me to
figure anything out. :)
Thanks

Hi,
I'm trying to run a selectionComputation with my own code for
VertexInputFormat but giraph' job starts to work and then fails with:
