*That leads to the following questions:

-Phadoop_yarn, the problem I was experiencing changed... I now see log
messages showing Girpah connecting to the Yarn ResourceManager on port

Hi all,
I'm new to Giraph, now I successfully ran my first example by following the
instruction on Giraph - Quick Start. However, I met a question when I write my
