> We found that Giraph jobs were consistently hanging if uppercase letters were included
in the DNS (or /etc/hosts) resolved hostnames ({{foo.stanford.edu}} vs. {{foo.Stanford.EDU}}
from our DNS).  Normalizing the hostnames to lower case from {{GiraphConfiguration#getLocalHostname()}}
fixed our problem.
