Hi, everybody,
I am learning Giraph. I have read the paper *pregel a system for
large-scale graph processing.*Although Giraph is based on pregel, I guess
it has added some extra features to improve the performances ( e.g.,
multi-threading). I wonder if I can get some introductions about technical
Hi Giraph Experts,
I'm trying to build Giraph (trunk) for Hadoop 2.4.0. I know that there are
2 profiles with which I can proceed to build. *hadoop_yarn* and *hadoop_2 *
profiles.
When I try with *hadoop_yarn*, build is fine. When I try with *hadoop_2*,
build is failing.
The commands I used is

Hey,
I am not aware of this error. Maybe ur Hadoop home is not correctly set or some

I don't know if u have access to this node. But if u do, u could check if the
file is indeed there and u have access to it.

Why r u adding two jars? Example jar ideally contains core library so
everything should be available with just one example jar included

Hi,
I remember seeing this thread, but since i was already deep into fixing this
issue in production, I didn't really wait for the patch, not even the munge
symbol as I was not even able to compile the yarn profile( sorry for being so
ruthless to giraph :-( )
I did later cross check with the pat
Hi Tripti,
let me add one info, As you can see from this thread of email:
http://mail-archives.apache.org/mod_mbox/giraph-user/201410.mbox/%3cc3f75a98-bde8-4205-971f-1f7241e6e...@yahoo.it%3E
I had some issue while compiling for Hadoop 2.5.1 could be that into the
process I loose something?

Hey,
Yeah I learnt it the hard way but -yj parameter doesn't need the full path like
I mentioned(I stated that it's just the file name as opposed to the full path u
give while mentioning Hadoop jar). Just try giving it the jar file name and not
the full path( say something like -yj
giraph-1.1.0
Hi Tripti,
yes I run in this way:
$HADOOP_INSTALL/bin/hadoop jar
/Users/ale/extprj/giraph/giraph-examples/target/giraph-examples-1.1.0-SNAPSHOT-for-hadoop-2.5.1-jar-with-dependencies.jar
org.apache.giraph.GiraphRunner
org.apache.giraph.examples.SimpleShortestPathsComputation -vif
org.apache.g
For GiraphApplicationMaster not found, the simple thing that worked for me was
adding a -yj parameter to my command.
(hadoop jar {jar-file-path} {path to giraph runner} {computation-class} {bunch
of parameters} -yj {jar-file-name})
If u look at job logs,
Do u see a log statement defining "LIB JAR
Hi,
yea my logs shows that error. I follow this example:
http://mail-archives.apache.org/mod_mbox/giraph-user/201408.mbox/%3c53f4c689.5060...@web.de%3E
without success.
Then I try to add all jars I can from giraph adding the following lines into
the hadoop-env.sh:
export
MYLIB=/opt/yarn/hadoop
