Hello everyone!
Apache Giraph is the most useful framework dealing with bigdata graphs.
But I have some difficulties about how to use it in my own custom project.
Little story about what has already done. I download giraph-1.2.0 and build
the next:
*mvn clean install -DskipTests -Dcheckstyle.skip=
Hi everyone,
I am new to giraph. I need to read from hive for my program. I cant find
any example or any documentation which clearly explains how we can do that
using giraph-hive. Tried reading through the code but its confusing.
Any help will be appreciated.
Thank you

Hi,
You have to make custom aggregator - Giraph is not designed for this use
case - this is little bit hacky.
I am not sure if MasterComputation is executed before first iteration.

Hi,
Thank you for the quick reply Lukas. I looked up aggregators at
org.apache.giraph.aggregators package but I am unable to find any
aggregator for graphs in that package. Can you tell me which
implementation of persistent aggregator I need to use or do I need to
implement a custom aggregator??

Hi,
You can also store the query graph to MR Distributed cache.

Hello Giraph Gurus,
I am interested in learning how to learn code custom graph algorithms using
Giraph.
I have some experience using MapReduce and have coded Graph Algorithms on
top of Hadoop. Now I want to learn how to do the same for Pregel (using
Giraph).
I have downloaded giraph-1.0.0 but
Hi fellow developers,
In the past day, I am struggling on completing calculating Betweeness for a
graph.
Browsing in some forums, some stated that this cannot be done.
This point of view is simply put WRONG!.

Hello Everyone,
I have a question about Giraph:
I could run all the example programs. I want to place my development
code in a different directory other than the giraph directory. I
copied the SimplePageRankComputation.java to a different directory,
compiled it(with a different package name). But
Great paper!

Hey,
Take a look at Apache Giraph; it's based on Google's Pregel paper. The
article below was put out by Facebook Engineering on how they use it.

Great article! Can you say something about your deployment in terms of
java version and jvm parameters (gc, max memory etc.)? It will be
useful to others, to learn best practices for such huge giraph jobs.

Hi Giraphers,
We recently released an article on we can use Giraph at the scale of a
trillion edges at Facebook. If you're interested, please take a look!

Just ran into it, great read. I hope that I will be able contribute again
in the future.
Awesome job done!

Hi Vishal,
This issue is due to Hadoop limiting the job counters.
org.apache.hadoop.mapred.Counters$CountersExceededException: Error:
Exceeded limits on number of counters - Counters=120 Limit=120
You can either disable the Giraph counters per superstep
(-Dgiraph.useSuperstepCounters=false),
