Eli:
Thanks. I was coming to that conclusion. The documentation is
out of sync and very sketchy.
I was basing this off of the README file in the 0.2 snapshot(line
173). It should not make a difference is the
cluster being submitted to is running local or or remote.
What is really missing is some basic documentation on exactly how
to run other examples other than
the PageRankBenchmark. Depending on priorities hopefully I will get
some time to mess around and
figure out one or two.
If anyone on the list has a small example program or test they
are willing to share I would be most
appreciative as that would help my target users significantly.

Just to throw this out there: it has been noted (by me most recently)
on the Giraph JIRA site that the tests aren't happy when you try to
run them against a running cluster, they like to instantiate their own
local resources (ZK, Hadoop single-node) for the tests. If your
example jobs run with "hadoop jar" on the cluster than thats what
matters, you're all set.

The maven surefire report for the test shows an assertion failure

Thanks that helps a great deal. I am now at least getting
to the point that the jobs show up in the job tracker.
However, they all
fail on initialization with the good old:
java.io.FileNotFoundException: File
/tmp/hadoop-mapred/mapred/staging/hdfs/.staging/job_201302211213_0055/job.jar
does not exist
This tells me that maven is either not specifying that the
giraph-core jar file should be used as the job jar or I am
missing
something else in the set up.
Attached is the job.xml file from one of the failed jobs and
below is the relevant profile out of my pom.xml.
I did upgrade to CDH4.1.3 just to see if that would help.
Also, I have been running all sorts of jobs (benchmarks, and
other tests) against this cluster for some time so I know
that the cluster
works well.
Again, any help is appreciated.
Relevant section of pom.xml:

Hi David,
Moving this to cdh-user, as it is CDH-specific.
CDH4 comes with two versions of mapreduce, MR1, and MR2. It
sounds like you are building against MR2
(http://blog.cloudera.com/blog/2012/10/mr2-and-yarn-briefly-explained/).
Do you know whether your cluster runs MR2/YARN or MR1? If
it runs, MR2, you can set mapreduce.framework.name
<http://mapreduce.framework.name> to "yarn". If it runs
MR1, you can build against the MR1 jar by setting the
version of your hadoop-client to 2.0.0-mr1-cdh4.1.1.
(https://ccp.cloudera.com/display/CDH4DOC/Managing+Hadoop+API+Dependencies+in+CDH4)
Does that help?

All:
I am trying to get the Giraph 0.2 snapshot (pulled
via GIT on Friday)
to build and run with CDH4.
I modified the pom.xml to provide a profile for my
specific version (4.1.1).
The build works (mvn -Phadoop_cdh4.1.1 clean package
test) and passes
all the tests.
If I try to do the next step and submit to my cluster
with the command:
mvn -Phadoop_cdh4.1.1 test
-Dprop.mapred.job.tracker=10.1.94.53:8021
<http://10.1.94.53:8021>
-Dgiraph.zkList=10.1.94.104:2181 <http://10.1.94.104:2181>
the JSON test in core fails. If I move that test out
of the way a whole bunch of tests in examples
fail. They all fail with:
java.io.IOException: Cannot initialize Cluster.
Please check your
configuration for mapreduce.framework.name
<http://mapreduce.framework.name> and the correspond
server
addresses.
I have tried passing mapreduce.framework.name
<http://mapreduce.framework.name> as both local and
classic. I have also set those values in my
mapreduce-site.xml.
Interestingly I can run the pagerank benchmark in code
with the command:
hadoop jar
./giraph-core/target/giraph-0.2-SNAPSHOT-for-hadoop-2.0.0-cdh4.1.3-jar-with-dependencies.jar
org.apache.giraph.benchmark.PageRankBenchmark
-Dmapred.child.java-opts="-Xmx64g -Xms64g
XX:+UseConcMarkSweepGC
-XX:-UseGCOverheadLimit"
-Dgiraph.zkList=10.1.94.104:2181
<http://10.1.94.104:2181> -e 1 -s 3 -v
-V 50000 -w 83
And it completes just fine.
I have searched high and low for documents and examples
on how to run the example programs from other
than maven but have not found any thing.
Any help or suggestions would be greatly appreciated.
THanks.
