Powered-by Giraph page
Hello giraphers, as Giraph is getting more visibility and users, I think it would be nice to add a Powered-by page on our site, were we collect names of companies that (want to share that) are using Giraph. So, this is basically a small survey about who is using Giraph. For those that I know: - Facebook Anybody else? Thanks! Claudio -- Claudio Martella
Re: Powered-by Giraph page
We have a guy from spotify on the list, who seems to be evaluating Giraph. You could ask whether they want to be on that page.

How to set giraph runtime parameters?
Hi, Does anybody know how to set runtime parameters in giraph? It should be set in command line or in a *.xml file? I tried -Dgiraph.zkSessionMsecTimeout=90( googled) in command line but failed. Thanks! Best Regards, Suijian
Re: How to set giraph runtime parameters?
you can set them on the command line, by using -D (e.g. -Dgiraph.isStaticGraph=true) after GiraphRunner, On Wed, Apr 9, 2014 at 4:44 PM, Suijian Zhou suijian.z...@gmail.com wrote: Hi, Does anybody know how to set runtime parameters in giraph?

Re: PageRank on custom input
Hi Vikesh, You just need to write an input format or use an existing one. You can specify any number and combination of VertexInputFormat and EdgeInputFormat formats as per your needs. Please see giraph-core/src/main/java/org/apache/giraph/io/formats for some examples.

zookeeper setting problem in giraph.
Hi, I have a problem in zookeeper in giraph, after the session has been established, it will lose connection in ~1 minute although I see the timeout is set to 60, i.e 10minutes.
